I got the answer

We need to add padding in Raised button for removing default padding

ButtonTheme(
      minWidth: 16.0,
      height: 30.0,
      child: RaisedButton(
        padding: const EdgeInsets.all(8.0),
        onPressed: () => print("a"),
        child: new Row(
          children: <Widget>[
            Padding(
              padding: const EdgeInsets.only(right: 6.0),
              child: Icon(
                Icons.filter,
                size: 16.0,
              ),
            ),
            Text(
              'FILTER',
              style: TextStyle(fontSize: 12.0),
            ),
          ],
        ),
      ),
    ),
