在行颤振中设置元素之间的间距

删除空间-：

new Row( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[   GestureDetector(     child: new Text('Don't have an account?',         style: new TextStyle(color: Color(0xFF2E3233))),     onTap: () {},   ),   GestureDetector(     onTap: (){},       child: new Text(     'Register.',     style: new TextStyle(         color: Color(0xFF84A2AF), fontWeight: FontWeight.bold),   )) ],          ),

要么

GestureDetector( onTap: (){}, child: new Row(   mainAxisAlignment: MainAxisAlignment.center,   children: <Widget>[     new Text('Don't have an account?',         style: new TextStyle(color: Color(0xFF2E3233))),     new Text(       'Register.',       style: new TextStyle(       color: Color(0xFF84A2AF), fontWeight: FontWeight.bold),     )   ], ),          ),
