[Enhancement] Make TextCaseConverter support ANY type

[dansiegel]

Summary

Currently the TextCaseConverter is pretty explicit about requiring that the value passed in must be null, a string, or a char... This is pretty silly as you may be passing in an Enum or a custom type with an overridden ToString.

XamarinCommunityToolkit/src/CommunityToolkit/Xamarin.CommunityToolkit/Converters/TextCaseConverter.shared.cs

Lines 27 to 30 in caa3ebc

	public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
	=> value == null || value is string || value is char
	? Convert(value?.ToString(), parameter)
	: throw new ArgumentException("Value is neither a string nor a char", nameof(value));

API Changes

Simply return the convert instead of type checking.

public object Convert(object value, Type targetType, object parameter, CultureInfo culture) 
 	=> Convert(value?.ToString(), parameter);

Intended Use Case

You may want to use this with an Enum or other custom type which overrides ToString. The only implication would be with ConvertBack and since that throws a NotImplementedException it's a non-issue.

Who Will Do The Work?

• I am willing to take this on myself
• Just putting this out there for someone to pick up
