Sharpnado.TaskLoaderView

v2.4.0

Free yourself from IsBusy=true! The `TaskLoaderView` is a UI component that handles all your UI loading state (Loading, Error, Result, Notification), and removes all the pain of async loading from your view models (try catch / async void / IsBusy / HasErrors / base view models / ...) thanks to its brother the `TaskLoaderNotifier`. BREAKING CHANGE Version 2.4.0: The task source given to to TaskLoaderNotifier is now a Func{bool, Task} (or a Func{bool, Task{T}}) instead of a Func{Task}. You can simply change your calls from Loader.Load(() => InitializeAsync()) to Loader.Load(_ => InitializeAsync()) to ignore it if you like. The boolean that is passed now to your task source is a boolean indicating if the notifier is refreshing. You can use it for invalidating your cache, for example: public Task LoadItems(bool isRefreshing) { if (isRefreshing || !_cache.ContainsItems()) { _cache.InvalidateItems(); var items = _httpService.GetItems() _cache.PutItems(items); return items; } return _cache.GetItems(); } Featuring: * Default views for all loading states (Loading, Error, Success, Notification, Refresh) * Snackbar component * Compose notifiers with CompositeTaskLoaderNotifier * Stylable views including fonts, accent color, error images, ... * Any states are overridable with user custom views and easily positionned with AbsoluteLayout properties * Support for Xamarin.Forms.Skeleton nuget package * Support for refresh scenarios, and error while refreshing with the ErrorNotificationView * Supports Async mvvm ICommand through TaskLoaderCommand * Supports loading task on demand with the NotStarted state * TaskLoaderNotifier for the ViewModel side taking care of all the error handling and the IsBusy nonsense
