M.BindableProperty.Generator 0.4.0

Maui.BindableProperty.Generator

Source generator that automatically transforms fields into BindableProperties that can be used in MAUI.

Installation

First, install NuGet. Then, install M.BindableProperty.Generator from the package manager console:

PM> Install-Package M.BindableProperty.Generator

Usage - Simple implementation

Just decorate field with the Bindable attribute.

    using Maui.BindableProperty.Generator.Core;

    public partial class CustomEntry : ContentView
    {
        [AutoBindable]
        private string _placeholder;
    }

the prevoius code will generate this:

    public partial class CustomEntry
    {
        public static readonly Microsoft.Maui.Controls.BindableProperty PlaceholderProperty = Microsoft.Maui.Controls.BindableProperty.Create(nameof(Placeholder), typeof(string), typeof(CustomEntry), default(string));
        public string Placeholder
        {
            get => (string)GetValue(PlaceholderProperty);
            set => SetValue(PlaceholderProperty, value);
        }
    }

Usage - Custom property name

Just decorate field with the Bindable attribute.

    using Maui.BindableProperty.Generator.Core;

    public partial class CustomEntry : ContentView
    {
        [AutoBindable(PropertyName = "Text")]
        private string _t;
    }

the prevoius code will generate this:

    public partial class CustomEntry
    {
        public static readonly Microsoft.Maui.Controls.BindableProperty TextProperty = Microsoft.Maui.Controls.BindableProperty.Create(nameof(Text), typeof(string), typeof(CustomEntry), default(string));
        public string Text
        {
            get => (string)GetValue(TextProperty);
            set => SetValue(TextProperty, value);
        }
    }

Usage - OnChanged method

Just decorate field with the Bindable attribute. The 'OnChanged' method must have only one parameter (must match the type of the field)

    using Maui.BindableProperty.Generator.Core;

    public partial class CustomEntry : ContentView
    {
        [AutoBindable(OnChanged = nameof(OnTextChanged))]
        private string _text;

        private void OnTextChanged(string newValue)
        { 
            // Do stuff here
        }
    }

the prevoius code will generate this:

    public partial class CustomEntry
    {
        public static readonly Microsoft.Maui.Controls.BindableProperty TextProperty = Microsoft.Maui.Controls.BindableProperty.Create(nameof(Text), typeof(string), typeof(CustomEntry), default(string));
        public string Text
        {
            get => (string)GetValue(TextProperty);
            set =>
            {
                SetValue(TextProperty, value);
                this.OnTextChanged(value);
            }
        }
    }
