Welcome to the Flutter API reference documentation.
|
||
|
||
Flutter is Google’s mobile UI framework for crafting high-quality native
|
||
interfaces on iOS and Android in record time. Flutter works with existing code,
|
||
is used by developers and organizations around the world, and is free and open
|
||
source.
|
||
|
||
The API reference herein covers all libraries that are exported by the Flutter
|
||
SDK.
|
||
|
||

### Importing a Library
|
||
|
||
#### Framework Libraries
|
||
|
||
Libraries in the "Libraries" section below (or in the left navigation) are part
|
||
of the core Flutter framework and are imported using
|
||
`'package:flutter/<library>.dart'`, like so:
|
||
|
||
```dart
|
||
import 'package:flutter/material.dart';
|
||
import 'package:flutter/services.dart';
|
||
```
|
||
|
||
#### Dart Libraries
|
||
|
||
Libraries in the "Dart" section exist in the `'dart:'` namespace and are imported
|
||
using `'dart:<library>'`, like so:
|
||
|
||
```dart
|
||
import 'dart:async';
|
||
import 'dart:ui';
|
||
```
|
||
|
||
Except for `'dart:core'`, you must import a Dart library before you can use it.
|
||
|
||
#### Other Libraries
|
||
|
||
Libraries in other sections are supporting libraries that ship with Flutter.
|
||
They are organized by package and are imported using
|
||
`'package:<package>/<library>.dart'`, like so:
|
||
|
||
```dart
|
||
import 'package:flutter_test/flutter_test.dart';
|
||
import 'package:file/local.dart';
|
||
```
|
||
|
||
### Finding Other Libraries
|
||
|
||
Flutter has a rich community of packages that have been contributed by the
|
||
open-source community. You can browse those packages at
