Transcript

  1. Flutter/Dart Google I/O 2017 報告会

  2. Flutterとは？ https://flutter.io/ AndroidとiOSのアプリのための SDK/Framework 現在アルファ

  3. Example

  4. 特徴 • Dartで開発する • Reactive • ネイティブコードに変換される • 単一のコードベースでAndroid/iOS両対応

  5. Reactive Widget build(BuildContext context) { return new Row( children: <Widget>[

    new RaisedButton( onPressed: increment, child: new Text('Increment'), ), new Text('Count: $counter'), ], ); }

  6. Native Code Android • C++部分はNDK Dart部分の大半はコンパイル iOS • C++部分はLLVM Dart部分はすべてAOTコンパイル(No

    interpreter)

  7. UI Framework 独自のUIフレームワークを内包している • プラットフォームのUIを使わないので、 Android/iOSの差異が小さい (コントロール可能) • Material/Cupatino(iOS)は選べる

  8. プラットフォーム連携 Java(Android)やSwift(iOS)のコードと連携可能

  9. Hot reload
