I have seen that I can\'t set the width of a RaisedButton in Flutter. If I have well understood, I should put the RaisedButton into a SizedBox
RaisedButton
SizedBox
i would recommend using a MaterialButton, than you can do it like this:
new MaterialButton( height: 40.0, minWidth: 70.0, color: Theme.of(context).primaryColor, textColor: Colors.white, child: new Text("push"), onPressed: () => {}, splashColor: Colors.redAccent, )
