does flutter work with any editors or IDEs? |
we provide plugins for VS code, |
android studio, and IntelliJ IDEA. |
see editor configuration for setup details, |
and VS code and android Studio/IntelliJ |
for tips on how to use the plugins. |
alternatively, you can use the flutter command |
from a terminal, along with one |
of the many editors that support editing dart. |

does flutter come with a framework? |
yes! flutter ships with a modern react-style framework. |
flutter’s framework is designed to be layered and |
customizable (and optional). developers can choose to |
use only parts of the framework, or even replace |
upper layers of the framework entirely. |

<topic_start> |
does flutter come with widgets? |
yes! flutter ships with a set of |
high-quality material design and cupertino |
(ios-style) widgets, layouts, and themes. |
of course, these widgets are only a starting point. |
flutter is designed to make it easy to create your own |
widgets, or customize the existing widgets. |

does flutter support material design? |
yes! the flutter and material teams collaborate closely, |
and material is fully supported. for more information, |
check out the material 2 and material 3 widgets |
in the widget catalog. |

does flutter come with a testing framework? |
yes, flutter provides APIs for writing unit and |
integration tests. learn more about testing with flutter. |
we use our own testing capabilities to test our SDK, |
and we measure our test coverage on every commit. |

does flutter come with debugging tools? |
yes, flutter comes with flutter DevTools (also |
called dart DevTools). for more information, see |
debugging with flutter and the flutter DevTools docs. |

does flutter come with a dependency injection framework? |
we don’t ship with an opinionated solution, |
but there are a variety of packages that offer |
dependency injection and service location, |
such as injectable, get_it, kiwi, and riverpod. |

what technology is flutter built with? |
flutter is built with c, c++, dart, |
skia (a 2d rendering engine), |
and impeller (the default rendering engine on iOS). |
see this architecture diagram |
for a better picture of the main components. |
for a more detailed description of the layered architecture |
of flutter, read the architectural overview. |

how does flutter run my code on android? |
the engine’s c and c++ code are compiled with android’s NDK. |
the dart code (both the SDK’s and yours) |
are ahead-of-time (aot) compiled into native, ARM, and x86 |
libraries. those libraries are included in a “runner” |
android project, and the whole thing is built into an .apk. |
when launched, the app loads the flutter library. |
