language (Dart, the same language used to build Flutter’s
framework). Flutter doesn’t ship with a declarative markup.We found that UIs dynamically built with code allow for
more flexibility. For example, we have found it difficult
for a rigid markup system to express and produce
customized widgets with bespoke behaviors.We have also found that our “code-first” approach better allows
for features like hot reload and dynamic environment adaptations.It’s possible to create a custom language that is then
converted to widgets on the fly. Because build methods
are “just code”, they can do anything,
including interpreting markup and turning it into widgets.<topic_end>

My app has a Debug banner/ribbon in the upper right. Why am I seeing that?
By default, the flutter run command uses the
debug build configuration.The debug configuration runs your Dart code in a VM (Virtual Machine)
enabling a fast development cycle with hot reload
(release builds are compiled using the standard Android
and iOS toolchains).The debug configuration also checks all asserts, which helps
you catch errors early during development, but imposes a
runtime cost. The “Debug” banner indicates that these checks
are enabled. You can run your app without these checks by
using either the --profile or --release flag to flutter run.If your IDE uses the Flutter plugin,
you can launch the app in profile or release mode.
For VS Code, use the Run > Start debugging
or Run > Run without debugging menu entries.
For IntelliJ, use the menu entries
Run > Flutter Run in Profile Mode or Release Mode.<topic_end>

What programming paradigm does Flutter’s framework use?
Flutter is a multi-paradigm programming environment.
Many programming techniques developed over the past few decades
are used in Flutter. We use each one where we believe
the strengths of the technique make it particularly well-suited.

Where can I get support?
If you think you’ve encountered a bug, file it in our
issue tracker. You might also use
Stack Overflow for “HOWTO” type questions.

How do I get involved?
Flutter is open source, and we encourage you to contribute.
You can start by simply filing issues for feature requests
and bugs in our issue tracker.We recommend that you join our mailing list at
[email protected] and let us know how you’re
using Flutter and what you’d like to do with it.If you’re interested in contributing code, you can start
by reading our Contributing guide, and check out our
list of easy starter issues.Finally, you can connect with helpful Flutter communities.

Which software license(s) apply to Flutter and its dependencies?
Flutter includes two components: an engine that ships as a
dynamically linked binary, and the Dart framework as a separate
binary that the engine loads. The engine uses multiple software
components with many dependencies; view the complete list
in its license file.The framework is entirely self-contained and requires
only one license.In addition, any Dart packages you use might have their
own license requirements.<topic_end>
<topic_start>
How can I determine the licenses my Flutter application needs to show?
There’s an API to find the list of licenses you need to show:If your application has a Drawer, add an
AboutListTile.If your application doesn’t have a Drawer but does use the
Material Components library, call either showAboutDialog
or showLicensePage.For a more custom approach, you can get the raw licenses from the
LicenseRegistry.<topic_end>

Who works on Flutter?
We all do! Flutter is an open source project.
Currently, the bulk of the development is done
by engineers at Google. If you’re excited about Flutter,
we encourage you to join the community and

Will Apple reject my Flutter app?
We can’t speak for Apple, but their App Store contains
many apps built with framework technologies such as Flutter.
Indeed, Flutter uses the same fundamental architectural
model as Unity, the engine that powers many of the
most popular games on the Apple store.Apple has frequently featured well-designed apps
that are built with Flutter,
including Hamilton and Reflectly.As with any app submitted to the Apple store,
apps built with Flutter should follow Apple’s
guidelines for App Store submission.
