横並び
Row(children: <Widget>[ Expanded(child: Container( padding: EdgeInsets.all(20.0), child: Text("1"), color: Colors.grey, ),), Expanded(child: Container( padding: EdgeInsets.all(20.0), child: Text("2"), color: Colors.red, ),), Expanded(child: Container( padding: EdgeInsets.all(20.0), child: Text("3"), color: Colors.green, ),), Expanded(child: Container( padding: EdgeInsets.all(20.0), child: Text("4"), color: Colors.blue, ),), ],),
上の20は高さ。

縦並び
Column( crossAxisAlignment: CrossAxisAlignment.center, children: <Widget>[ Text('taro'), Text('jiro'), Text('saburo') ], ),
参考:https://dev.classmethod.jp/smartphone/flutter_column_row_1/
左詰め
child: Column( crossAxisAlignment: CrossAxisAlignment.start,
上詰め
child: Column( mainAxisAlignment: MainAxisAlignment.start,
これは違う?
比率
横並びの比率をflexで入れる。
Row( children: [ Expanded( flex: 2, child: Container( color: Colors.blue, child: Text('taro'), ), ), Expanded( flex: 3, child: Container( color: Colors.green, child: Text('jiro'), ), ), Expanded( flex: 1, child: Container( color: Colors.orange, child: Text('saburo'), ), ), ], ),

1つの部品と残りの部品の比率
Row( children: [ Flexible( flex: 1, child: Container( color: Colors.blue, child: Text('taro'), ), ), Flexible( flex: 10, child: Container( color: Colors.green, child: Text('jiro'), ), ), ], ),
縦方向に比率表示
これはエラーが出るみたい・・・。
Column( children: <Widget>[ Expanded( flex: 3, child: Container( color: Colors.green, ), ), Expanded( flex: 2, child: Container( color: Colors.red, ), ) ], ),
参考:https://note.com/norisato/n/n9ae6e24b52a7
左右中央
Center( child: Column( children: <Widget>[ Text("hogehoge"), ], ),
上下左右中央
Center( child: Column( mainAxisSize: MainAxisSize.min, children: <Widget>[ Text("hogehoge"), ], ), ),
