Add a hover GestureRecognizer

[jmagman]

Use case

The hover gesture is an important one on devices with mouse support, particularly when designing flutter for web. A HoverGestureRecognizer would make it easier, for example, to add a recognizer to a TextSpan.

Proposal

Create a GestureRecognizer HoverGestureRecognizer, similar to TapGestureRecognizer.

[DSenanayake]

Agreed!

I need it!!

[kenthinson]

Hover is already built in Listener()
However it seems to be broken on web. Not sure about other platforms as i did not test.

[DSenanayake]

@kenthinson yes, it's only working when you mouse down and enter.

@jmagman I have opened a issue to fix the bug. #33707
As it's not a feature request but rather a bug fix this one should be closed?

[jmagman]

I still think it would be nice to have a built-in hover GestureRecognizer that can be used to create a TextSpan.

@jmagman Can you illustrate what you want to achieve by this addition that can't (easily) be done with MouseRegion.onHover (which used to be Listener.onHover when this issue was opened)? Only with a clear application can we start to discuss the best way to design a new API.

@dkwingsmt MouseRegion takes Widget child, and can't convert InlineSpan TextSpan to Widget. Is that right?

Why closed? Is HoverGestureRecognizer already exist or how handle PointerHoverEvent on TextSpan?

All widgets now receive hover events. The gesture recognizer of TextSpan should receive hover events now (although I haven't specifically tested this one).

@dkwingsmt Thank you for your answer! But i not understand how handle hover event on TextSpan. Can you help me? How i can write custom gesture recognizer for PointerHoverEvent?

[gsx123]

I have same question about how to handle hover event on TextSpan.
Can any one show the demo code?
