ensureInitialized static method
Returns an instance of the ElementsBinding, creating and initializing it if necessary. If one is created, it will be a ElementsFlutterBinding. If one was previously initialized, then it will at least implement ElementsBinding.
Implementation
static ElementsBinding ensureInitialized() {
if (ElementsBinding.instance == null) ElementsFlutterBinding();
return ElementsBinding.instance!;
}
