Detailed Design

public interface INotificationCounter
{
	Task<bool> RequestPermission();
	void SetNotificationCount(int count);
}

Usage Syntax

var isGranted = await NotificationCounter.Default.RequestPermission();
if (isGranted)
    NotificationCounter.Default.SetNotificationCount(count);

Drawbacks

Android implementation requires the support of many launchers. As part of this feature, I suggest creating a base class and implementation for some main providers, because we can’t support all launchers

Thanks @VladislavAntonyuk!

Promoting to https://github.com/CommunityToolkit/Maui/labels/approved as we voted to approve it in the December Standup.

Technically, we should’ve opened the Proposal first before voting to approve said Proposal, but we’ll let this one slide.

Submitting a Proposal doesn’t require a vote from the core maintainers. It should start as a Discussion, and then once the Discussion is deemed feature-complete a Proposal can be opened.
