MaterialStateBorderSide class Null safety

Defines a BorderSide whose value depends on a set of MaterialStates which represent the interactive state of a component.

To use a MaterialStateBorderSide, you should create a subclass of a MaterialStateBorderSide and override the abstract resolve method.

This example defines a subclass of MaterialStateBorderSide, that resolves to a red border side when its widget is selected.
To create a local project with this code sample, run:
flutter create --sample=material.MaterialStateBorderSide.1 mysample

This class should only be used for parameters which are documented to take MaterialStateBorderSide, otherwise only the default state will be used.
