Feature request: ability to pause and resume the slide show

[abhlabs]

Maybe this can already be done, but I haven't figured out how to do it. I'd like to have a button underneath the slide show that's labeled "Pause" or "Resume" based on whether the slide show is in a currently paused state or not, and have the onPressed() handler call a "pause" or "resume" function. You can't just set the autoPlayInterval to 0 -- the ImageSlideshow class has that set as final.

If you consider adding this feature, it might be nice to also accept a tap on the slide slow to pause or resume.

I created a fork of the current flutter_image_slideshow repository with a possible solution to pause / resume. I'm not entirely happy with it though, it relies on a callback to check to see if the user has asked for the slideshow to be paused or resumed, and that callback has to be made repeatedly (after some experimentation, I decided 1/4 second was fast enough that users would perceive instantaneous response).

I don't like the idea of having to do continuous callbacks, but I wasn't able to come up with a better solution.

Sorry for the late reply!

Do you want to control the "Pause" and "Resume" of the slideshow?

Actually you can use several feature like "goToPage" and "stopAutoPlay".
Please refer to this PR(#9 ).
Can't you use this feature?

Thanks, I missed seeing that in the changelog on pub.dev. I see the "stopAutoPlay" -- which seems easy enough, but how do you resume? Is it as simple as performing a "goToPage" with the next page in sequence?

Didn't see any way to resume, so I did a pull request to incorporate that feature.

Thanks for pull request👍
I'll review it!
