Implementation
@override
Future<bool> routeExists(String routeName) async {
// debugPrint('Flutter开始调用:method:${FMNavigatorMethod.routeExists}');
final ret = await methodChannel.invokeMethod<bool>(
FMNavigatorMethod.routeExists,
{
'routeName': routeName,
},
);
// debugPrint('Flutter结束调用:method:${FMNavigatorMethod.routeExists}');
return ret ?? false;
}
