Flutter中Container铺满问题

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Container"),
      ),
      body: Container(
        width: 200,
        height: 200,
        color: Colors.red,
        child: Container(
          width: 100,
          height: 100,
          color: Colors.blue,
        ),
      ),
    );
  }

解决办法：设置第一个Container的alignment即可
