FmgLib.MauiMarkup 8.6.2

FmgLib.MauiMarkup

FmgLib.MauiMarkup is a specialized library crafted for .NET MAUI. This library allows you to code directly in C# without the necessity of employing XAML language. It provides developers with a straightforward and flexible approach to building user interfaces using C# code. With FmgLib.MauiMarkup, you can now develop application interfaces in a code-focused manner, avoiding the complexities of dealing with XAML files. This library accelerates your development process while enabling you to write more readable and manageable code.

FmgLib.MauiMarkup provides extension methods for all properties provided for a View on the XAML side.

For example:

If we were to write XAML code for the Image class, it would look like this:

<Image
    Source="dotnet_bot.png"
    HeightRequest="100"
    WidthRequest="150"
    Grid.Row="0"
    Grid.Column="1"
    Grid.RowSpan="2"
    Opacity=".8" />

The C# equivalent with the help of FmgLib.MauiMarkup would be as follows:

new Image()
.Source("dotnet_bot.png")
.Row(0)
.Column(1)
.RowSpan(2)
.SizeRequest(150,100)
.Opacity(.8)

Similarly, we can see this for other Views. Let's write a few sample codes as an example:

new Label()
.Text("fmglib.mauimarkup")
.FontSize(12)
.Row(1)
.TextColor(Colors.Green)
.FontAttributes(FontAttributes.Bold)
.Margin(new Thickness(5,3,0,5))

this
.BackgroundImageSource("background.jpg")
.Content(
    new StackLayout()
    .Center()
    .Children(
        new ActivityIndicator()
        .IsRunning(true)
        .HeightRequest(70)
        .WidthRequest(70)
        .Center()
        .InvokeOnElement(ai => ai.Loaded += CheckLogin(sender, e))
    )
);

Extensions for 3rd Party Controls

FmgLib.MauiMarkup library can also generate extension methods for controls from third-party libraries. To achieve this, you should utilize the MauiMarkupAttribute provided by FmgLib.MauiMarkup.

Simply specify the control for which you want to create extension methods as [MauiMarkup(typeof(YourControl))].

The constructor method of the MauiMarkup() attribute automatically generates extension methods for BindableProperties and Events found within the type provided as an argument. You can provide a minimum of 1 type inside the constructor method, and there is no maximum limit. Multiple MauiMarkup attributes can be added to a single class.

Let's look at an example:

using FmgLib.MauiMarkup;

namespace GeneratedExam;

[MauiMarkup(typeof(ZXing.Net.Maui.Controls.BarcodeGeneratorView))]
public class MyBarcodeGeneratorView { }

[MauiMarkup(typeof(ZXing.Net.Maui.Controls.CameraView))]
public class MyCameraView { }


[MauiMarkup(typeof(ZXing.Net.Maui.Controls.CameraBarcodeReaderView))]
public class MyCameraBarcodeReaderView { }

[MauiMarkup(typeof(SkiaSharp.Extended.UI.Controls.SKLottieView))]
public class MySkLottieView { }

[MauiMarkup(typeof(InputKit.Shared.Controls.FormView))]
public class MyFormView { }

Or instead of dealing with it like this, it can be used like this:

using Microsoft.Extensions.Logging;
using FmgLib.MauiMarkup;
using SkiaSharp.Extended.UI.Controls;
using ZXing.Net.Maui.Controls;
using UraniumUI.Material.Controls;
namespace MauiApp1
{
    [MauiMarkup(typeof(CameraView))]
    [MauiMarkup(typeof(SKLottieView), typeof(SKFileLottieImageSource), typeof(DataGrid))]
    [MauiMarkup(typeof(SKConfettiView), typeof(BarcodeGeneratorView),typeof(InputField),typeof(EditorField),typeof(TextField))]
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                    fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
                });

#if DEBUG
    		builder.Logging.AddDebug();
#endif
            return builder.Build();
        }
    }
}

With the MauiMarkupAttachedPropAttribute, you can easily create extension methods for AttachedProperties within Control classes from third-party libraries. The constructor's first parameter takes the type of the Control class, the second parameter takes the name of the AttachedProperty, the third parameter takes the value type that the AttachedProperty can accept, and the fourth parameter takes the type to which the AttachedProperty will be applied.

Example usage:

[MauiMarkupAttachedProp(typeof(InputKit.Shared.Controls.FormView), nameof(InputKit.Shared.Controls.FormView.IsSubmitButtonProperty), typeof(bool), typeof(Button))]
[MauiMarkup(typeof(InputKit.Shared.Controls.FormView))]
public class MyFormView { }

OR

using Microsoft.Extensions.Logging;
using FmgLib.MauiMarkup;

namespace MauiApp1
{
    [MauiMarkupAttachedProp(typeof(InputKit.Shared.Controls.FormView), nameof(InputKit.Shared.Controls.FormView.IsSubmitButtonProperty), typeof(bool), typeof(Button))]
    [MauiMarkup(typeof(InputKit.Shared.Controls.FormView))]
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                    fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
                });

#if DEBUG
    		builder.Logging.AddDebug();
#endif
            return builder.Build();
        }
    }
}

The usage of the AttachedProperty in the Button class will be as follows:

new Button()
.Text("Login")
.FontAttributes(Bold)
.IsSubmitButton(true)

For example, let's write the sample code for the TextField and SKLottieView Controls:

new TextField()
.Title("Password")
.TitleColor(Colors.LightGray)
.AccentColor(Colors.CadetBlue)
.TextColor(Colors.White)
.IsPassword(true),

new SKLottieView()
.Source(new SKFileLottieImageSource().File("iconapp.json"))
.RepeatCount(-1)
.HeightRequest(250)
.WidthRequest(250)

Genral Example Code:

using Microsoft.Maui.Layouts;
using FmgLib.MauiMarkup;

namespace MyOrderApp.Views;

public partial class HomePage : BasePage<HomePageViewModel>
{
    public HomePage(HomePageViewModel viewModel) : base(viewModel, "Home Page")
    {
    }

    public override void Build()
