feat: support resetting TileLayer

[tprebs]

This change supports the clearing of in memory tiles from the TileLayerState as described in #666

I created a separate Stream to manage reset events instead of using the LayerOptions rebuild stream as this is currently consumed by the onMove event subscriber and any changes to this may affect existing implementations using the rebuild.

I have also added an example for resetting the a TileLayer

Any news?

@JaffaKetchup, I can bring this PR inline with master this weekend if required. I haven't looked at this in a few months

[JaffaKetchup]

Don't worry about it, it would just be nice to have, and improve the experience of my plugin especially.

[antonshkurenko]

@tprebs would be great!

[JaffaKetchup]

@tprebs If you're busy, I can bring it up to date now for you?

[antonshkurenko]

I would love to have this merged!

[JaffaKetchup]

Don't like to ask again, but any hope of this coming soon? @tprebs

[tprebs]

@JaffaKetchup sorry for the delay, it's been a busy couple of months. I have brought the PR up to master. I have also been planning on making the feaflet heatmap plugin available but there are just not enough hours in the day

LGTM. Thanks for the contribution!

[JaffaKetchup]

@tprebs Thanks, and don't worry about the delay, it's similar story for me. Great that you've finally found time to do it!

[JaffaKetchup]

@kengu Thanks for all the merges today :), is there a pub.dev update planned any time soon to publish these changes?

PS. You haven't merged #989, correct me if I'm wrong, but I'm assuming you need another maintainers approval as it was originally written by you?

[kengu]

Yes, I'm not allowed to approve my own PRs, so we need to wait on @johnpryan or some of the other contributors with write access to master.
