Answer 1

Put your AppBar widget as a child of Container and set margin to EdgeInset.all(4). This should work.

Try Following code :

appBar: PreferredSize(
      preferredSize:  Size.fromHeight(70.0),
      child: Container(
              padding: EdgeInset.all(4), // you can change this value to 8 
            child:AppBar(
            ...
