如何在Flutter中设置按钮的最小尺寸？

Question

按钮小部件的代码：

class UploadTextButton extends StatelessWidget {
  final Function _onPressed;

  const UploadTextButton(this._onPressed);

  @override
  Widget build(BuildContext context) {
    return Container(
      constraints: BoxConstraints(
        maxWidth: 250,
        maxHeight: 50,
        minWidth: 200,
        minHeight: 50
      ),
      child: OutlinedButton(
        style: ButtonStyle(
          minimumSize: MaterialStateProperty.all(Size(200, 50))
        ),
          onPressed: () => _onPressed(),
          child: Row(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              Padding(
                padding: const EdgeInsets.only(right: 8.0),
                child: Icon(Icons.cloud_upload),
              ),
              Text("Upload my new picture")
            ],
          )),
    );
  }
}

如果测试大小有问题，可以使用FittedBox()小部件处理文本。

FittedBox(
child:Text("Upload my new picture"),)
