Creating custom Controls (Is there a better way?)

[MDale-RAC]

When creating a ContentView is there a more concise way to add BindablePropertys?

For instance (in the Code-Behind):

public partial class ProfileDetailView: ContentView
{
	public static readonly BindableProperty EmailProperty =
		BindableProperty.Create(nameof(Email), typeof(string), typeof(LoginView), string.Empty);

	public string Email
	{
		get => (string)GetValue(EmailProperty);
		set => SetValue(EmailProperty, value);
	}

	[...]
}

Seems, to me, incredibly verbose when compared to what is available in ObservableObject (for ViewModels) using the ObservablePropertyAttribute:

[ObservableProperty]
private string _email = string.Empty;

I understand these are different paradigms for different use-cases, but is there a way to generate the above (BindableProperty and getter/setter) with a similar type of attribute? For instance, say (naively):

public partial class ProfileDetailView: ContentView
{
	[BindableProperty]
	private string _email = string.Empty;
	// Auto-generate:
	// 	|- public static readonly BindableProperty EmailProperty
	//		\- propertyName: Email
	//		  \- returnType: typeof(string)
	//		    \- declaringType: typeof(ProfileDetailView)
	//		      \- defaultValue: string.Empty (?? this I am dubious/unsure of ??)
	// 	|- public string Email
	//		\- getter (cast GetValue of EmailProperty)
	//		  \- setter (SetValue for EmailProperty using value)

	[...]
}

Does this already exist perhaps? (If so, would someone be so kind as to direct me to that documentation? I didn't see it, but perhaps I don't know the right term for it!)

Many thanks in advance!

There're nuget packages that do it for you, we have an open spec for that but isn't started yet.

[MDale-RAC]

Sorry, but your reply is ambiguous to me:

• "[There are] nuget packages" (what nuget packages?)
• "open spec for that" (what is "that"?)

What keywords would you suggest looking for?

Any chance you could provide any links to what you are referencing?

@MDale-RAC the spec is the potential design for it, for people to discuess how it should be implemented before someone starts to work on it - #542

There are existing nuget packages that you could use, such as - https://github.com/rrmanzano/maui-bindableproperty-generator

@IeuanWalker thanks you beat me to it!
