Flutter - AppBar Bottom widget
I wanted to ask, because I get a lot of errors, if it is possible to place a Divider() widget like this:
AppBar(
bottom: Divider()
)
And if yes, could anyone show me how it's possible to do that

If you read the bottom documentation, it must implement PreferredSizeWidget and Divider does not implement it.
But you can create your own version and use it there.
class MyDivider extends Divider implements PreferredSizeWidget {
MyDivider({
Key key,
height = 16.0,
indent = 0.0,
color,
}) : assert(height >= 0.0),
super(
key: key,
height: height,
indent: indent,
color: color,
) {
preferredSize = Size(double.infinity, height);
}
@override
Size preferredSize;
}

Could you tell what is not working? If I do AppBar(title: Text("Title"), bottom: MyDivider(color: red) ) I can see a one pixel red line in the bottom of my bar.
