WidgetStateOutlinedBorder class abstract
Defines an OutlinedBorder whose value depends on a set of WidgetStates which represent the interactive state of a component.
To use a WidgetStateOutlinedBorder, you should create a subclass of an
OutlinedBorder and implement WidgetStateOutlinedBorder's abstract
resolve method.
This example defines a subclass of RoundedRectangleBorder and an
implementation of WidgetStateOutlinedBorder, that resolves to
RoundedRectangleBorder when its widget is selected.

To create a local project with this code sample, run:
flutter create --sample=widgets.WidgetStateOutlinedBorder.1 mysample
This class should only be used for parameters which are documented to take WidgetStateOutlinedBorder, otherwise only the default state will be used.
