maybePop<T extends Object> method

  1. @optionalTypeArgs
Future<bool> maybePop <T extends Object>(BuildContext context, [ T result ])
@optionalTypeArgs

Returns the value of the current route's Route.willPop method for the navigator that most tightly encloses the given context.

This method is typically called before a user-initiated pop. For example on Android it's called by the binding for the system's back button.

The T type argument is the type of the return value of the current route. See also:

  • Form, which provides an onWillPop callback that enables the form to veto a pop initiated by the app's back button.
  • ModalRoute, which provides a scopedWillPopCallback that can be used to define the route's willPop method.

@optionalTypeArgs
static Future<bool> maybePop<T extends Object>(BuildContext context, [ T result ]) {
  return Navigator.of(context).maybePop<T>(result);
