问题：在一个Android原生的弹框里显示flutter view,由于使用了Expanded导致组件未显示出来

最神奇的地方在于debug调试模式显示正常，然后用release版本发布时怎么都显示不出来，还导致点击后无响应ANR

问题代码：

child: StatefulBuilder(builder: (context, setState) {return Expanded(child: Container(padding: const EdgeInsets.fromLTRB(10, 0, 10, 0),decoration: BoxDecoration(borderRadius: newStyle? const BorderRadius.only(topLeft: Radius.circular(12),topRight: Radius.circular(12),bottomLeft: Radius.circular(0),bottomRight: Radius.circular(0),): BorderRadius.circular(4),color: themeData.fillBase),child: Column(mainAxisAlignment: MainAxisAlignment.start,crossAxisAlignment: CrossAxisAlignment.stretch,children: _buildSettingColumn(),),),);},),

修改后代码：

child: StatefulBuilder(builder: (context, setState) {return Container(width: 200,padding: const EdgeInsets.fromLTRB(10, 0, 10, 0),decoration: BoxDecoration(borderRadius: newStyle? const BorderRadius.only(topLeft: Radius.circular(12),topRight: Radius.circular(12),bottomLeft: Radius.circular(0),bottomRight: Radius.circular(0),): BorderRadius.circular(4),color: themeData.fillBase),child: Column(mainAxisAlignment: MainAxisAlignment.start,crossAxisAlignment: CrossAxisAlignment.stretch,children: _buildSettingColumn(),),);},),

总结：自己挖的坑给自己上了一课，过程中最困难的是release版本有问题时难以定位，最后还是回退代码才发现的。
