# Deprecated settings.gradle
This project is meant to test that apps using the deprecated
`android/settings.gradle` (_PluginEach_ used until Flutter v1.22.0) can still be built.
This project can be removed once apps have been migrated to this new file.

# API Example Code
This directory contains the API sample code that is referenced from the API
documentation in the framework.
The examples can be run individually by just specifying the path to the example
on the command line (or in the run configuration of an IDE).
For example (no pun intended!), to run the first example from the `Curve2D`
class in Chrome, you would run it like so from the [api](.) directory:
```
% flutter run -d chrome lib/animation/curves/curve2_d.0.dart
```
All of these same examples are available on the API docs site. For instance, the
example above is available on [this page](
https://api.flutter.dev/flutter/animation/Curve2D-class.html#animation.Curve2D.1).
Most of the samples are available as interactive examples in
[Dartpad](https://dartpad.dev), but some (the ones marked with `{@tool sample}`
in the framework source code), just don't make sense on the web, and so are
available as standalone examples that can be run here. For instance, setting the
system overlay style doesn't make sense on the web (it only changes the
notification area background color on Android), so you can run the example for
that on an Android device like so:
```
% flutter run -d MyAndroidDevice lib/services/system_chrome/system_chrome.set_system_u_i_overlay_style.1.dart
```
## Naming
> `lib/library/file/class_name.n.dart`
>
> `lib/library/file/class_name.member_name.n.dart`
The naming scheme for the files is similar to the hierarchy under
[packages/flutter/lib/src](../../packages/flutter/lib/src), except that the
files are represented as directories (without the `.dart` suffix), and each
sample in the file is a separate file in that directory. So, for the example
above, where the examples are from the
[packages/flutter/lib/src/animation/curves.dart](../../packages/flutter/lib/src/animation/curves.dart)
file, the `Curve2D` class, the first sample (hence the index "0") for that
symbol resides in the file named
[lib/animation/curves/curve2_d.0.dart](lib/animation/curves/curve2_d.0.dart).
Symbol names are converted from "CamelCase" to "snake_case". Dots are left
between symbol names, so the first example for symbol
`InputDecoration.prefixIconConstraints` would be converted to
`input_decoration.prefix_icon_constraints.0.dart`.
If the same example is linked to from multiple symbols, the source will be in
the canonical location for one of the symbols, and the link in the API docs
block for the other symbols will point to the first symbol's example location.
## Authoring
> For more detailed information about authoring examples, see
> [the snippets package](https://pub.dev/packages/snippets).
When authoring examples, first place a block in the Dartdoc documentation for
the symbol you would like to attach it to. Here's what it might look like if you
wanted to add a new example to the `Curve2D` class:
```dart
/// {@tool dartpad}
/// Write a description of the example here. This description will appear in the
/// API web documentation to introduce the example.
///
/// ** See code in examples/api/lib/animation/curves/curve2_d.0.dart **
/// {@end-tool}
```
The "See code in" line needs to be formatted exactly as above, with no wrapping
or newlines, one space after the "`**`" at the beginning, and one space before
the "`**`" at the end, and the words "See code in" at the beginning of the line.
This is what the snippets tool use when finding the example source code that you
are creating.
Use `{@tool dartpad}` for Dartpad examples, and use `{@tool sample}` for
examples that shouldn't be run/shown in Dartpad.
Once that comment block is inserted in the source code, create a new file at the
appropriate path under [`examples/api`](.). See the
[sample_templates](./lib/sample_templates/) directory for examples of different
types of samples with some best practices applied.
The filename should match the location of the source file it is linked from, and
is named for the symbol it is attached to, in lower_snake_case, with an index
relating to their order within the doc comment. So, for the `Curve2D` example
above, since it's in the `animation` library, in a file called `curves.dart`,
and it's the first example, it should have the name
`examples/api/lib/animation/curves/curve2_d.0.dart`.
You should also add tests for your sample code under
[`examples/api/test`](./test), that matches their location under [lib](./lib),
ending in `_test.dart`. See the section on [writing tests](#writing-tests) for
more information on what kinds of tests to write.
The entire example should be in a single file, so that Dartpad can load it.
Only packages that can be loaded by Dartpad may be imported. If you use one that
hasn't been used in an example before, you may have to add it to the
[pubspec.yaml](pubspec.yaml) in the api directory.
## Snippets
There is another type of example that can also be authored, using `{@tool
snippet}`. Snippet examples are just written inline in the source, like so:
```dart
/// {@tool dartpad}
/// Write a description of the example here. This description will appear in the
/// API web documentation to introduce the example.
///
/// ```dart
/// // Sample code goes here, e.g.:
/// const Widget emptyBox = SizedBox();
/// ```
/// {@end-tool}
```
The source for these snippets isn't stored under the [`examples/api`](.)
directory, or available in Dartpad in the API docs, since they're not intended
to be runnable, they just show some incomplete snippet of example code. It must
compile (in the context of the sample analyzer), but doesn't need to do
anything. See [the snippets documentation](
https://pub.dev/packages/snippets#snippet-tool) for more information about the
context that the analyzer uses.
## Writing Tests
Examples are required to have tests. There is already a "smoke test" that simply
builds and runs all the API examples, just to make sure that they start up
without crashing. Functionality tests are required the examples, and generally
just do what is normally done for writing tests. The one thing that makes it
more challenging to do for examples is that they can't really be written for
testability in any obvious way, since that would complicate the examples and
make them harder to explain.
As an example, in regular framework code, you might include a parameter for a
`Platform` object that can be overridden by a test to supply a dummy platform,
but in the example. This would be unnecessarily complex for the example. In all
other ways, these are just normal tests. You don't need to re-test the
functionality of the widget being used in the example, but you should test the
functionality and integrity of the example itself.
Tests go into a directory under [test](./test) that matches their location under
[lib](./lib). They are named the same as the example they are testing, with
`_test.dart` at the end, like other tests. For instance, a `LayoutBuilder`
example that resides in [`lib/widgets/layout_builder/layout_builder.0.dart`](
./lib/widgets/layout_builder/layout_builder.0.dart) would have its tests in a
file named [`test/widgets/layout_builder/layout_builder.0_test.dart`](
./test/widgets/layout_builder/layout_builder.0_test.dart)

## Directory contents
The `.yaml` files in these directories are used to
define the [`dart fix` framework](https://dart.dev/tools/dart-fix) refactorings
used by the Flutter framework.
The number of fix rules defined in a file should not exceed 50 for better
maintainability. Searching for `title:` in a given `.yaml` file will account
for the number of fixes. Splitting out fix rules should be done by class.
When adding a new `.yaml` file, make a copy of `fix_template.yaml`. If the new
file is not for generic library fixes (`fix_material.yaml`), ensure it is
enclosed in an appropriate library directory (`fix_data/fix_material`), and
named after the class. Fix files outside of generic libraries should represent
individual classes (`fix_data/fix_material/fix_app_bar.yaml`).
See the flutter/packages/flutter/test_fixes directory for the tests that
validate these fix rules.
To run these tests locally, execute this command in the
flutter/packages/flutter/test_fixes directory.
```sh
dart fix --compare-to-golden
```
For more documentation about Data Driven Fixes, see
https://dart.dev/go/data-driven-fixes#test-folder.
To learn more about how fixes are authored in package:flutter, see
https://github.com/flutter/flutter/wiki/Data-driven-Fixes
## When making structural changes to this directory
The tests in this directory are also invoked from external
repositories. Specifically, the CI system for the dart-lang/sdk repo
runs these tests in order to ensure that changes to the dart fix file
format do not break Flutter.
See [tools/bots/flutter/analyze_flutter_flutter.sh](https://github.com/dart-lang/sdk/blob/main/tools/bots/flutter/analyze_flutter_flutter.sh)
for where the tests are invoked.
When possible, please coordinate changes to this directory that might affect the
`analyze_flutter_flutter.sh` script.
