FLUTTER | Right Align not working

问题:

Trying to right align a container with text view child, it has a row parent which is inside another column, tried number of solutions from Stack Overflow, didn't work.

Code

///Transactions Heading
        new Column(
         children: <Widget>[
            new Row(
              children: <Widget>[
                new Container(
                  alignment: Alignment.centerLeft,
                  margin: new EdgeInsets.only(top: 20.0, left: 10.0),
                  child: new Text(
                    "Transactions",
                    style: new TextStyle(
                      color: primaryTextColor,
                      fontSize: 25.0,
                      fontWeight: FontWeight.w700,
                      letterSpacing: 0.1,
                    ),
                  ),
                ),
                new Container(
                  margin: new EdgeInsets.only(top: 25.0),
                  child: new Text(
                    currentGoalTransactions.length.toString() + " items",
                    style: new TextStyle(
                        color: darkHeadingsTextColor, fontSize: 15.0),
                  ),
                ),
              ],
            ),
       ]);

Use the mainAxisAlignment property in Row widget.

new Row(
    mainAxisAlignment: MainAxisAlignment.spaceBetween, 
    ...
)
