Add support for ReorderableGridView.builder() #13

Closed renannery closed 2 years ago

renannery commented 3 years ago

When dealing with a large list, it can get pretty slow while scrolling.

I understand the implementation is different and quite challenging, but something to consider support for better performance.

karvulf commented 3 years ago

Hello @renannery

Thank you for your feedback. I will take a look to improve the performance. I have some ideas.

karvulf commented 2 years ago

I released a new release candidate for the version 2.0.0. I added the implementations for all types of GridViews, including GridView.builder. This also improve the performance generally.

If you want to try that, you can use the version 2.0.0-dev.1.

Thank you! I've just tested and apparently, the animation stopped working when items are moving position in the gridview. In my implementation, there is no user interaction with drag-and-drop, the elements change their positions randomly according to our API and until version 1.1.5 it works just fine.

Switching to 2.0.0-dev.1 using the default constructor ReorderableGridView() the animation won't work

karvulf commented 2 years ago

Ah ok, this implementation is still in process. Currently I only have rebuilt the drag and drop functionality. The animation type is a bit more difficult, but if I am successfull, there will be another widget, that you can only use for that type of animation, sth like AnimatedReorderableGridView or both of them combined. @renannery

There is a new update for the release candidate. I added the missing animation for all types in the GridView. For ReorderableWrap it is currently not supported.

You can test2.0.0-dev.2. There you also should have a better performance when using ReorderableGridView.builder. @renannery

You can find more information about this update in the CHANGELOG.md.
