AnimatedModalBarrier class
A widget that prevents the user from interacting with widgets behind itself, and can be configured with an animated color value.
The modal barrier is the scrim that is rendered behind each route, which generally prevents the user from interacting with the route below the current route, and normally partially obscures such routes.
For example, when a dialog is on the screen, the page below the dialog is usually darkened by the modal barrier.
This widget is similar to ModalBarrier except that it takes an animated color instead of a single color.

Methods
-
build(
BuildContext context) → Widget -
Override this method to build widgets that depend on the state of the
listenable (e.g., the current value of the animation).
override
-
createElement(
) → StatefulElement -
Creates a StatefulElement to manage this widget's location in the tree.
inherited
-
createState(
) → State< AnimatedWidget> -
Subclasses typically do not override this method.
inherited
-
debugDescribeChildren(
) → List< DiagnosticsNode> -
Returns a list of DiagnosticsNode objects describing this node's
children.
inherited
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toDiagnosticsNode(
