About The Project

Awaitable Popups is a neat blend of the Rg.Plugins.Popup and AsyncAwaitBestPractices plugins to bring you a quick way to add popups into your Xamarin Forms App using familiar concepts

Built With

• Rg.Plugins.Popup
• AsyncAwaitBestPractices

Getting Started

First, you must follow the initialisation guide set out by Rg.Plugins.Popup, once you have that, have a look at usage down below

Installation

You can install the nuget by looking up 'AwaitablePopups' in your nuget package manager, or by getting it here

Usage

here is an example of what this plugin makes easy (Looks slow due to giphy)

New Example

To Use the plugin for its inbuilt popup pages in a basic setting (Dual/Single Response, Login, TextInput EntryInput,and loader.) All you need are these one liners

SingleResponse Popup Page

return await SingleResponseViewModel.AutoGenerateBasicPopup(Color.HotPink, Color.Black, "I Accept", Color.Gray, "Good Job, enjoy this single response example", "thumbsup.png");

DualResponse Popup Page

return await DualResponseViewModel.AutoGenerateBasicPopup(Color.WhiteSmoke, Color.Red, "Okay", Color.WhiteSmoke, Color.Green, "Looks Good!", Color.DimGray, "This is an example of a dual response popup page", "thumbsup.png");

Loader Popup Page

  await PopupService.WrapTaskInLoader(Task.Delay(10000), Color.Blue, Color.White, LoadingReasons(), Color.Black);

Text Input PopupPage

await TextInputViewModel.AutoGenerateBasicPopup(Color.WhiteSmoke, Color.Red, "Cancel", Color.WhiteSmoke, Color.Green, "Submit", Color.DimGray, "Text input Example", string.Empty);

Entry Input PopupPage

await EntryInputViewModel.AutoGenerateBasicPopup(Color.WhiteSmoke, Color.Red, "Cancel", Color.WhiteSmoke, Color.Green, "Submit", Color.DimGray, "Text input Example", string.Empty);

LoginPage PopupPage

var (username, password) = await LoginViewModel.AutoGenerateBasicPopup(Color.WhiteSmoke, Color.Red, "Cancel", Color.WhiteSmoke, Color.Green, "Submit", Color.DimGray, string.Empty, "Username Here", string.Empty, "Password here", "thumbsup.png", 0, 0);

or, to return from the loader a value

await PopupService.WrapReturnableTaskInLoader<bool, LoaderPopupPage>(IndepthCheckAgainstDatabase(), Color.Blue, Color.White, LoadingReasons(), Color.Black);

you can also add in synchronous functions, however they are wrapped in a task

private bool LongRunningFunction(int millisecondDelay)
{
    Thread.Sleep(millisecondDelay);
    return true;
}
await PopupService.WrapReturnableFuncInLoader(LongRunningFunction, 6000, Color.Blue, Color.White, LoadingReasons(), Color.Black);

That's it! for advanced usage read on

In Version 1.1.0, AwaitablePopups will be starting on a new set of API's

This set of API's will be used for when the basic API wont cut it, without relying on me making another overload for every situation under the sun.

This API introduces

GeneratePopup<TPopupPage> Which allows you to supply your own popuppage xaml which will then be attached to whatever VM you called it from.

GeneratePopup(Dictionary<string, object> propertyDictionary) Which allows you have a dictionary of values that a popup uses, pass and automatically attach to the appropriate properties on the VM side

These are both non-static. and require you to have an instance of the ViewModel to work with. Hence

<ViewModelClassNameHere>.GenerateVM() Which provides you with a new instance of that VM

<ViewModelClassNameHere>.PullViewModelProperties() Which collects all the properties of a VM, and provides them to you in a dictionary, so you can reuse and also while debugging, check what exists/whats been changed Returns this Dictionary<string, (object property, Type propertyType)>

However, for initialisation, i internally (and you can use) the following function <ViewModelClassNameHere>.InitialiseOptionalProperties(Dictionary<string, object> optionalProperties) Which will attempt to set each of the viewmodel properties with the corrosponding value in the dictionary

So, to fix that, i provide <ViewModelClassNameHere>.FinalisePreparedProperties(Dictionary<string, (object property, Type propertyType)> viewModelProperties) Which takes in the Dictionary<string, (object property, Type propertyType)> and creates Dictionary<string, object> optionalProperties

Hopefully i will add on to make this easier in the future

If you want to make your own Popup Page

This is the real power of this Plugin (Thanks in no small amount to Rotorgames amazing plugin). If you look at the source for DualResponsePopupPage, or the SingleResponse version you'll notice that they are just simple Xaml Pages. Nothing fancy. (except for the rg popup spice).

You can create the full thing yourself

1. Create Xaml Page with codebehind
2. Create your ViewModel that is associated with the popup, lets call ours InformationPopupPage
3. Ensure your ViewModel inherits from PopupViewModel<TReturnable> where TReturnable is what you want the popuppage to return to its caller
4. Ensure that your xaml page codebehind inherits from PopupPage (requirement to use rg plugins popup) and IGenericViewModel<TViewModel> where TViewModel is your Viewmodel, in our case it will be IGenericViewModel<InformationPopupPage>
5. You're ready to start using it the same as DualResponsePopupPage

New API Usage (1.1.0) or you can provide your own Xaml Page, with a codebehind that inherits from PopupPage and IGenericViewModel<TViewModel> where TViewModel is the plugin provided VM you wish to use.

to use this version, just call TViewModel.GeneratePopup<YourXamlPopupPage>()
