Challenge Solution
How was it? Easy? Difficult? Let’s go ahead and show how to do this. If you look through the code, you will see a method named: areYouSureDelete. This will show a dialog promting the user to answer Yes or No. In order to use this dialog you’ll need a context. Searching through the code shows that we can get the current context from the global navigatorKey: navigatorKey.currentContext.
Android Studio
Here’s the full code:
final listController = ref.read(listControllerProvider);
final todoList = listController.currentList;
if (todoList.name != 'empty') {
areYouSureDelete(navigatorKey.currentContext!,
'Are you sure you want to delete ${todoList.name}',
(deleted) {
if (deleted) {
final repository = ref.read(repositoryProvider);
repository.deleteTodoList(todoList);
}
});
}
