昨天在pub.dev上闲逛，发现一个挺有意思的程序包：photo_manager，决定尝试一下。
废话不多，直接上代码
flutter create flutterdemo01
然后用vscode打开，在终端运行：
flutter pub add photo_manager
安装包。
Widget build(BuildContext context) { PhotoManager.requestPermissionExtend(); return Scaffold( appBar: AppBar( title: Text(widget.title), ), body: Center( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ Text( ‘You have pushed the button this many times:‘, ), Text( ‘$_counter‘, style: Theme.of(context).textTheme.headline4, ), ], ), ), floatingActionButton: FloatingActionButton( onPressed: _incrementCounter, tooltip: ‘Increment‘, child: Icon(Icons.add), ), // This trailing comma makes auto-formatting nicer for build methods. ); }
编译一下试试，经过漫长等待，终于。。。。。。。。。。。。。。。。。。报错了。

好吧，搜一下:photo_manager:compileDebugKotlin，还真有人踩过这个坑，
