initMethod method

@override Future<void> initMethod(BuildContext context, { required String appId, bool showNativeUI = false, Widget? customWidget(Map<String, dynamic> response)?, })

context is required to show dialog isShowNative is used to show customWidget isShowNative turn it off if you want to show your customWidget you can show your customWidget ui

Implementation

@override
Future<void> initMethod(
  BuildContext context, {
  required String appId,
  bool showNativeUI = false,
  Widget? Function(Map<String, dynamic> response)? customWidget,
}) async {
  WidgetsBinding.instance.addPostFrameCallback((timeStamp) async {
    this.context = context;
    final result = await methodChannel.invokeMethod(
        'setApplicationID', {"AppId": appId, "showNativeUI": showNativeUI});
    if (result) {
      _listenToNativeMethod();
      final appUpdateResponse = await _check();
      if (customWidget != null) {
        final widget = customWidget.call(appUpdateResponse);

        ///custom ui dialog
        if (!showNativeUI && widget != null) {
          _alertDialog(widget);
        }
      }
    }
  });
}
