The non-abstract class '_CustomNavigatorState' is missing implementations

[sgehrman]

I just updated to the latest flutter beta:

../../../.pub-cache/hosted/pub.dartlang.org/custom_navigator-0.3.0/lib/custom_navigator.dart:60:7: Error: The non-abstract class '_CustomNavigatorState' is missing implementations for these members:

• WidgetsBindingObserver.didPushRouteInformation Try to either
• provide an implementation,
• inherit an implementation from a superclass or mixin,
• mark the class as abstract, or
• provide a 'noSuchMethod' implementation.

class _CustomNavigatorState extends State<CustomNavigator> ^^^^^^^^^^^^^^^^^^^^^ ../../../google/flutter/packages/flutter/lib/src/widgets/binding.dart:122:16: Context: 'WidgetsBindingObserver.didPushRouteInformation' is defined here. Future didPushRouteInformation(RouteInformation routeInformation) { ^^^^^^^^^^^^^^^^^^^^^^^ Failed to compile application. Exited (sigterm)

@override
  Future<bool> didPushRouteInformation(RouteInformation routeInformation) {
    return didPushRoute(routeInformation.location);
  }

Thanks @iNoles, it works, adding the implementation in custom_navigator.dart solves the problem.

[shrutika-tatkare-apptware]

I did tested with it and introduced a new bug.

The method 'call' was called on null.
Receiver: null
Tried calling: call()

on widget.onItemTap(index);

Use this in your pubspec.yaml

 custom_navigator:
    git:
      url: https://github.com/kjawadDeveloper/Custom-navigator.git

@kjawadDeveloper You saved my day. Thank you.

Use this in your pubspec.yaml

 custom_navigator:
    git:
      url: https://github.com/kjawadDeveloper/Custom-navigator.git

This solution solved the build error but seems to cause another problem. When a tab item is clicked, it is supposed to show the tab page immediately but if several pages are stacked up by Navigator.push, they only gets Navigator.pop.

Changed the package to another one. I found this okay. https://pub.dev/packages/persistent_bottom_nav_bar
