negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the

# Doxyfile 1.9.4
# This file is a template for the Doxyfile used to generate Flutter
# documentation for the Engine code using Doxygen. Fields with
# @@FIELD_NAME@@ as the value will be substituted by the
# tools/gen_docs.sh script to contain the appropriate values for a
# specific documentation section configured in the script.
# This file describes the settings to be used by the documentation system
# doxygen (www.doxygen.org) for a project.
#
# All text after a double hash (##) is considered a comment and is placed in
# front of the TAG it is preceding.
#
# All text after a single hash (#) is considered a comment and will be ignored.
# The format is:
# TAG = value [value, ...]
# For lists, items can also be appended using:
# TAG += value [value, ...]
# Values that contain spaces should be placed between quotes (\" \").
#
# Note:
#
# Use doxygen to compare the used configuration file with the template
# configuration file:
# doxygen -x [configFile]
# Use doxygen to compare the used configuration file with the template
# configuration file without replacing the environment variables or CMake type
# replacement variables:
# doxygen -x_noenv [configFile]
#---------------------------------------------------------------------------
# Project related configuration options
#---------------------------------------------------------------------------
# This tag specifies the encoding used for all characters in the configuration
# file that follow. The default is UTF-8 which is also the encoding used for all
# text before the first occurrence of this tag. Doxygen uses libiconv (or the
# iconv built into libc) for the transcoding. See
# https://www.gnu.org/software/libiconv/ for the list of possible encodings.
# The default value is: UTF-8.
DOXYFILE_ENCODING = UTF-8
# The PROJECT_NAME tag is a single word (or a sequence of words surrounded by
# double-quotes, unless you are using Doxywizard) that should identify the
# project for which the documentation is generated. This name is used in the
# title of most generated pages and in a few other places.
# The default value is: My Project.
PROJECT_NAME = "@@PROJECT_NAME@@"
# The PROJECT_NUMBER tag can be used to enter a project or revision number. This
# could be handy for archiving the generated documentation or if some version
# control system is used.
PROJECT_NUMBER =
# Using the PROJECT_BRIEF tag one can provide an optional one line description
# for a project that appears at the top of each page and should give viewer a
# quick idea about the purpose of the project. Keep the description short.
PROJECT_BRIEF =
# With the PROJECT_LOGO tag one can specify a logo or an icon that is included
# in the documentation. The maximum height of the logo should not exceed 55
# pixels and the maximum width should not exceed 200 pixels. Doxygen will copy
# the logo to the output directory.
PROJECT_LOGO = ./docs/flutter_logo.png
# The OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) path

# option can be useful when feeding doxygen a huge amount of source files, where
# putting all generated files in the same directory would otherwise causes
# performance problems for the file system. Adapt CREATE_SUBDIRS_LEVEL to
# control the number of sub-directories.
# The default value is: NO.
# For Flutter, this should be NO, so that URLs remain stable across versions.
CREATE_SUBDIRS = NO
# Controls the number of sub-directories that will be created when
# CREATE_SUBDIRS tag is set to YES. Level 0 represents 16 directories, and every
# level increment doubles the number of directories, resulting in 4096
# directories at level 8 which is the default and also the maximum value. The
# sub-directories are organized in 2 levels, the first level always has a fixed
# number of 16 directories.
# Minimum value: 0, maximum value: 8, default value: 8.
# This tag requires that the tag CREATE_SUBDIRS is set to YES.
CREATE_SUBDIRS_LEVEL = 8
# If the ALLOW_UNICODE_NAMES tag is set to YES, doxygen will allow non-ASCII
# characters to appear in the names of generated files. If set to NO, non-ASCII

# U+3044.
# The default value is: NO.
ALLOW_UNICODE_NAMES = NO
# The OUTPUT_LANGUAGE tag is used to specify the language in which all
# documentation generated by doxygen is written. Doxygen will use this
# information to generate all constant output in the proper language.
# Possible values are: Afrikaans, Arabic, Armenian, Brazilian, Bulgarian,
# Catalan, Chinese, Chinese-Traditional, Croatian, Czech, Danish, Dutch, English
# (United States), Esperanto, Farsi (Persian), Finnish, French, German, Greek,

# The default value is: YES.
REPEAT_BRIEF = YES
# This tag implements a quasi-intelligent brief description abbreviator that is
# used to form the text in various listings. Each string in this list, if found
# as the leading text of the brief description, will be stripped from the text
# and the result, after processing the whole list, is used as the annotated
# text. Otherwise, the brief description is used as-is. If left blank, the

FULL_PATH_NAMES = YES
# The STRIP_FROM_PATH tag can be used to strip a user-defined part of the path.

SHORT_NAMES = NO
# If the JAVADOC_AUTOBRIEF tag is set to YES then doxygen will interpret the

# The default value is: NO.
JAVADOC_AUTOBRIEF = NO
# If the JAVADOC_BANNER tag is set to YES then doxygen will interpret a line
# such as
# /***************
# as being the beginning of a Javadoc-style comment "banner". If set to NO, the

QT_AUTOBRIEF = NO
# The MULTILINE_CPP_IS_BRIEF tag can be set to YES to make doxygen treat a
# multi-line C++ special comment block (i.e. a block of //! or /// comments) as
# a brief description. This used to be the default behavior. The new default is
# to treat a multi-line C++ comment block as a detailed description. Set this

#
# Note that setting this tag to YES also means that rational rose comments are
# not recognized any more.
# The default value is: NO.
MULTILINE_CPP_IS_BRIEF = NO
# By default Python docstrings are displayed as preformatted text and doxygen's

# If the INHERIT_DOCS tag is set to YES then an undocumented member inherits the
# documentation from any documented member that it re-implements.
# The default value is: YES.
INHERIT_DOCS = YES
# If the SEPARATE_MEMBER_PAGES tag is set to YES then doxygen will produce a new
# page for each member. If set to NO, the documentation of a member will be part
# of the file/class/namespace that contains it.
# The default value is: NO.
SEPARATE_MEMBER_PAGES = NO
# The TAB_SIZE tag can be used to set the number of spaces in a tab. Doxygen

# Minimum value: 1, maximum value: 16, default value: 4.
TAB_SIZE = 4
# This tag can be used to specify a number of aliases that act as commands in
# the documentation. An alias has the form:
# name=value
# For example adding
# "sideeffect=@par Side Effects:^^"
# will allow you to put the command \sideeffect (or @sideeffect) in the
# documentation, which will result in a user-defined paragraph with heading
# "Side Effects:". Note that you cannot put \n's in the value part of an alias
# to insert newlines (in the resulting output). You can put ^^ in the value part
# of an alias to insert a newline as if a physical newline was in the original
# file. When you need a literal { or } or , in the value part of an alias you
# have to escape them by means of a backslash (\), this can lead to conflicts
# with the commands \{ and \} for these it is advised to use the version @{ and
# @} or use a double escape (\\{ and \\})
ALIASES =
# Set the OPTIMIZE_OUTPUT_FOR_C tag to YES if your project consists of C sources

# The default value is: NO.
OPTIMIZE_OUTPUT_FOR_C = NO
# Set the OPTIMIZE_OUTPUT_JAVA tag to YES if your project consists of Java or

# The default value is: NO.
OPTIMIZE_OUTPUT_SLICE = NO
# Doxygen selects the parser to use depending on the extension of the files it
# parses. With this tag you can assign which parser to use for a given
# extension. Doxygen has a built-in mapping, but you can override or extend it
# using this tag. The format is ext=language, where ext is a file extension, and
# language is one of the parsers supported by doxygen: IDL, Java, JavaScript,
# Csharp (C#), C, C++, Lex, D, PHP, md (Markdown), Objective-C, Python, Slice,
# VHDL, Fortran (fixed format Fortran: FortranFixed, free formatted Fortran:
# FortranFree, unknown formatted Fortran: Fortran. In the later case the parser
# tries to guess whether the code is fixed or free formatted code, this is the
# default for Fortran type files). For instance to make doxygen treat .inc files
# as Fortran files (default is PHP), and .f files as C (default is Fortran),
# use: inc=Fortran f=C.
#
# Note: For files without extension you can use no_extension as a placeholder.
#
# Note that for custom extensions you also need to set FILE_PATTERNS otherwise
# the files are not read by doxygen. When specifying no_extension you should add
# * to the FILE_PATTERNS.

AUTOLINK_SUPPORT = YES
# If you use STL classes (i.e. std::string, std::vector, etc.) but do not want

# The default value is: NO.
SIP_SUPPORT = NO
# For Microsoft's IDL there are propget and propput attributes to indicate
# getter and setter methods for a property. Setting this option to YES will make

# The size of the symbol lookup cache can be set using LOOKUP_CACHE_SIZE. This

# doxygen will become slower. If the cache is too large, memory is wasted. The
# cache size is given by this formula: 2^(16+LOOKUP_CACHE_SIZE). The valid range
# is 0..9, the default is 0, corresponding to a cache size of 2^16=65536

// TODO (kaushikiska): In the future there may be times where specific

// Typically these allow for the gpu to read cpu writes from the cache
// without needing to flush the writes throughout the cache. The reverse
// is not true and GPU writes tend to invalidate the cache regardless.
// Also these gpu cache read access are typically lower bandwidth than
// non-cached memory. For now Skia doesn't really have a need or want of

# The Impeller Shader Compiler & Reflector
Host side tooling that consumes [GLSL 4.60 (Core
Profile)](https://www.khronos.org/registry/OpenGL/specs/gl/GLSLangSpec.4.60.pdf)
shaders and generates libraries suitable for consumption by an Impeller backend.
Along with said libraries, the reflector generates code and meta-data to
construct rendering and compute pipelines at runtime.

to add the `--enable-vulkan-validation-layers` to the `gn` invocation to make
sure the layers are built and injected into the Flutter jar.
Example:
```sh
flutter/tools/gn \
--runtime-mode=debug \
--enable-vulkan-validation-layers \
--no-lto \
--unoptimized \
--android \
--android-cpu=arm64
```
Then adding the following field to the
`android/app/src/main/AndroidManifest.xml` will turn them on:
```xml
<meta-data
android:name="io.flutter.embedding.android.EnableVulkanValidation"
android:value="true" />
```

# Frequently Asked Questions
* How do I enable Impeller to try it out myself?
* See the instructions in the README on how to [try Impeller in
Flutter](https://github.com/flutter/engine/tree/main/impeller#try-impeller-in-flutter).
* Support on some platforms is further along than on others. The current
priority for the team is to support iOS, Android, Desktops, and Embedder API
users (in that rough order).
* I am running into issues when Impeller is enabled, how do I report them?
* Like any other Flutter issue, you can report them on the [GitHub issue
tracker](https://github.com/flutter/flutter/issues/new/choose).
* Please explicitly mention that this is an Impeller specific regression. You
can quickly swap between the Impeller and Skia backends using the command
line flag flag detailed in [section in the README on how to try
Impeller](https://github.com/flutter/engine/tree/main/impeller#try-impeller-in-flutter).
* Reduced test cases are the most useful.
* Please also report any performance regressions.
* What does it mean for an Impeller platform to be "in preview". How long will
be the preview last?
* The team is focused on getting one platform right at a time. This includes
ensuring all fidelity issues are fixed, performance issues addressed, and
compatibility with plugins guaranteed.
* When the team believes that the majority of Flutter applications will
benefit from Impeller on a specific platform, the backend will be declared
to be in preview.
* During the preview, Flutter developers will need to opt in to using
Impeller.
* The top priority of the team will be to address issues reported by
developers opting into the preview. The team wants the preview phase for a
platform to be as short as possible.
* Once major issues reported by platforms in preview become manageable, the
preview ends and Impeller becomes the default rendering backend.
* Besides working on fixing issues reported on platforms in preview, and
working on supporting additional platforms, the team is also undertaking a
high-touch exercise of migrating large existing Flutter applications to use
Impeller. The team will find and fix any issues it encounters during this
exercise.
* The length of the preview will depend on the number and nature of the issues
filed by developers and discovered by the team.
* Even once the preview ends, the developer can opt into the legacy rendering
backend for a short period of time. The legacy backend will be removed after
this period.
* What can I expect when I opt in to using Impeller?
* A high level overview of the status of project is [present on the
wiki](https://github.com/flutter/flutter/wiki/Impeller#status).
* All Impeller related work items are tracked on a [project specific dashboard
on GitHub](https://github.com/orgs/flutter/projects/21).
* The team tracks known platform specific issues in their own milestones:
* [iOS](https://github.com/flutter/flutter/milestone/77)
* [Android](https://github.com/flutter/flutter/milestone/76)
* Does Impeller use Skia for rendering?
* No. Impeller has no direct dependencies on Skia.
* When running with Impeller, Flutter does not create a Skia graphics context.
* However, while Impeller still performs text rendering, text layout and
shaping needs to be done by a separate component. This component happens to
be SkParagraph which is part of Skia.
* Similarly, Impeller does not perform image decompression. Flutter uses a
standard set of codecs wrapped by Skia before querying the system supplied
image formats.
* So, while Impeller does not use nor is a wrapper for Skia, some Skia
components are still used by Flutter when rendering using Impeller.
* Is Impeller going to be supported on the Web?
* The current priority for Impeller is to be amazing on all platforms targeted
by the C++ engine. This includes iOS, Android, desktops, and, all Embedder
API users. This would be by building Metal, Open GL, Open GL ES, and, Vulkan
rendering backends.
* The Open GL ES backend ought to work fine to target WebGL/WebGL2 and the
team can fix any issues found in such uses of the backend.
* However, in Flutter, Impeller sits behind the Display List interface in the
C++ engine. Display lists apply optimizations to the Flutter rendering
intent. But, more importantly for Impeller, they also provide a generic
interface with the ability to specify "dispatchers" to different rendering
packages. Today, the engine has Skia and Impeller dispatchers for display
lists.
* The web engine is unique in that it doesn't use any C++ engine components.
This includes the display lists mechanism. Instead, it interfaces directly
with Skia via the CanvasKit package.
* Updating the web engine to interface directly with Impeller is a non-goal at
this time. It is a significant undertaking (compared to a flag to swap
dispatchers that already exists) and also bypasses display list
optimizations.
* For this added implementation complexity, Web support has not been a
priority at this time for the small team working on Impeller.
* We are aware that these priorities might change in the future. There have
been sanity checks to ensure that the Impeller API can be ported to WASM and
also that Impeller shaders can be [compiled to
WGSL](https://github.com/chinmaygarde/wgsl_sandbox) for eventual WebGPU
support.
* How will Impeller affect the way in which Flutter applications are created and
packaged?
* It won't.
* Impeller, like Skia, is an implementation detail of the Flutter Engine.
Using a different rendering package will not affect the way in which the
Flutter Engine is used.
* Like with Skia today, none of Impellers symbols will be exposed from the
Flutter Engine dynamic library.
* The binary size overhead of Impeller is around 100 KB per architecture. This
includes all precompiled shaders.
* Impeller is compiled into the Flutter engine. It is currently behind a flag
as development progresses.
* How do you run `impeller_unittests` with Playgrounds enabled?
* Specify the `--enable_playground` command-line option.
