Better Maui Converters

Sample app for better ways of working with IValueConverter's in Maui

When using a value converter, there is alot of boilerplate type checking to perform. Also when you test the converter you have to to extra casting (since the return type of IValueConverter is object).

This sample provides 2 base classes which perform the casting & type checking, all your converter needs to do is specify the value & return types:

public class YourConverter : ConverterBase<string, Color>
{
	public Color Convert(string value, Type TargetType, object? parameter, CultureInfo culture)
    {
        ...
    }
    
    public string ConvertBack(Color value, Type TargetType, object? parameter, CultureInfo culture)
    {
        ...
    }
}

Add parameter as the third type argument:

public class YourConverter : ConverterBase<string, Color, int>
{
	public Color Convert(string value, Type TargetType, int parameter, CultureInfo culture)
    {
        ...
    }
    
    public string ConvertBack(Color value, Type TargetType, int parameter, CultureInfo culture)
    {
        ...
    }
}

Currently this is just a sample project, I think these classes could be useful in a library, however I need to battle test them first!
