Answer 1

If I understand correctly, you want to add a left button to your AppBar . You can achieve that by using the leading property, like this:

AppBar(
  title: Text("AppBar with leading button"),
  automaticallyImplyLeading: false,
  leading: IconButton (
                 icon: Icon(Icons.arrow_back), 
                 onPressed: () { 
                       /** Do something */ 
                 },
            ),
)

Answer 2

To insert a widget on the left side of an Appbar, you must use the property: "leading" , in addition to this, you can increase the width of this widget with the property: "leadingWidth"

appbar: AppBar(
  leading: Widget(),
  leadingWidth: 100
 )
