flutter - Flutter FlatButton内部空间

Question

在我的一个flutter应用程序中，有一个FlatButton，如下所示

FlatButton(
   child: Text("Forgot ist ?",
       style: TextStyle(color: Color.fromRGBO(107, 106, 106, 1),fontFamily: 'ActoBook'),
       textAlign: TextAlign.left
   ),

   materialTapTargetSize: MaterialTapTargetSize.shrinkWrap,
   splashColor: Colors.transparent,  
   highlightColor: Colors.transparent,
   shape: RoundedRectangleBorder(
      borderRadius: new BorderRadius.circular(0.0),
      side: BorderSide(color: Colors.transparent),
   ),
   onPressed: (){
       Navigator.pushReplacement(context, new MaterialPageRoute( builder: (context) => LoginPage()),);
  },
)

如何使按钮的文本右对齐？当前，它以左右相等的空间居中。

目前显示像这样

+-----------------+
|   Button Text   |
+-----------------+

我正在尝试使其像

+-----------------+
|      Button Text|
+-----------------+

可以正常运行，请检查一下。

FlatButton(
        padding: EdgeInsets.zero,
        color: Colors.blue,
        // wrap the text in a container and give it a specified width
        child: Container(
          width: 100,
          child: Text(
            "Forgot ist ?",
            style: TextStyle(
              color: Color.fromRGBO(107, 106, 106, 1),
              fontFamily: 'ActoBook',
            ),
            // set the alignment of the text to TextAlign.end
            textAlign: TextAlign.end,
          ),
        ),
        materialTapTargetSize: MaterialTapTargetSize.shrinkWrap,
        splashColor: Colors.transparent,
        highlightColor: Colors.transparent,
        shape: RoundedRectangleBorder(
          borderRadius: new BorderRadius.circular(0.0),
          side: BorderSide(color: Colors.transparent),
        ),
        onPressed: () {
        Navigator.pushReplacement(context, new MaterialPageRoute( builder: (context) => LoginPage()),);
        },
      )),

上面的代码给出以下输出:
