FlutterでTextFieldを最下部に配置する

Last updated at Posted at 2018-07-01

こんなのを作る

どうやるのか

TextFiledを最下部に配置するには、以下のように全体をColumnでwrapし、TextFiledの上に配置するWidgetをExpandedでwrapします。

new Column(
  children: <Widget>[
    new Expanded(
      child: new SingleChildScrollView(
        child: new Column(
          children: <Widget>[
            new Container(
              padding: new EdgeInsets.all(5.0),
              child: new Text(
                "Test",
                style: new TextStyle(fontWeight: FontWeight.bold),
              ),
            ),
            new Container(
              padding: new EdgeInsets.all(5.0),
              child: new Text(
                "Test",
                style: new TextStyle(fontWeight: FontWeight.bold),
              ),
            ),
          ],
        ),
      ),
    ),
    new TextField(
      autofocus: true,
      style: new TextStyle(
        fontSize: 20.0,
        color: Colors.black,
      ),
      controller: _controller,
      decoration: new InputDecoration(
        border: InputBorder.none,
        hintText: 'コメントを追加',
      ),
    ),
  ],
)
