How do you create a button with an image using Flutter? It seems like the simplest thing to do, but the image does not fill the parent widget completely. This is what I have:
Container(child: ConstrainedBox(
constraints: BoxConstraints.expand(),
child: FlatButton(onPressed: null,
child: Image.asset('path/the_image.png'))))
I followed this post as guidance. My image looks like this:
Notice the padding around the PNG image - it's not in the code. Where does it come from? The PNG itself does not have canvas padding, so this must not be the correct technique.
All I need is a button with an image that fills the entire FlatButton
, or another widget I can add actions to, without distorting the image.
I think this should work as well. Just specify the padding for the FlatButton to zero.
Container(child: ConstrainedBox(
constraints: BoxConstraints.expand(),
child: FlatButton(
onPressed: null,
padding: EdgeInsets.all(0.0),
child: Image.asset('path/the_image.png'))))
