Flutter采坑日记

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。
