How to add increase /configure weight/boldness (FontWeight) of an Icon in Flutter

icon size

Container(
child: Icon(
    Icons.arrow_back,
    color: Color(0xffffffff),
    size: 24.0
 ),
 padding: EdgeInsets.all(10.0),
 margin: EdgeInsets.fromLTRB(0, 10.0, 0, 0.0),
 decoration: BoxDecoration(
    color: Color(0xff03b673),
    borderRadius: BorderRadius.all(Radius.circular(100.0)),
 ),
)

At the moment,I think there is no fontWeight property on icons. you may import custom icon from fluttericon.com and when you import it under fonts you can set the font weight like this in pubspec.yaml:

flutter:
 fonts:
 - family: MyIcon
  fonts:
    - asset: lib/fonts/iconfont.ttf
      weight: 400
