How To Place AppBar Title in Left Side in Flutter

Here is my code for AppBar Tittle, but it not Working

 Widget build(BuildContext context){
return new Scaffold(
  appBar: new AppBar(
    title: new Padding(
      padding: const EdgeInsets.only(left: 20.0),
      child: new Text("App Name"),
    ),
  ),
);}

Transform is the widget used for forcefully translating widgets in the x-y-z dimensions.

return Scaffold(
        appBar: AppBar(
          centerTitle: false,
          titleSpacing: 0.0,
          title:  Transform(
              // you can forcefully translate values left side using Transform
              transform:  Matrix4.translationValues(-20.0, 0.0, 0.0),
              child: Text(
                "HOLIDAYS",
                style: TextStyle(
                  color: dateBackgroundColor,
                ),
              ),
            ),
        ),
      );
