Same here using StaggeredGridView inside a NestedScrollView when trying to scroll.

[Theunodb]

Also having this problem.

[jarekb123]

Also having this issue.

[dereklakin]

It's something to do with the hitTestChildren method in SliverVariableSizeBoxAdapter. If I revert it to just call super.hitTestChildren then scrolling works, but onTap on my child items never fires, so there's more to it than that :)

[dereklakin]

I've fixed it for my scenario, though I'm not sure if it will work for everyone. In sliver_variable_size_box_adaptor.dart change hitTestChildren method to:

  bool hitTestChildren(HitTestResult result,
      {@required double mainAxisPosition, @required double crossAxisPosition}) {
    for (var child in children) {
      if (hitTestBoxChild(BoxHitTestResult.wrap(result), child,
          mainAxisPosition: mainAxisPosition,
          crossAxisPosition: crossAxisPosition)) return true;
    }
    return false;
  }

The important bit is the change to call BoxHitTestResult.wrap(result) in the call to hitTestBoxChild instead of just passing result.

[korbacsk]

Same problem.

This Fixed the problem for me..

[cmcgill1988]

Any news if the PR fixing this is going to get merged in? I'm keen to use this package but until this is fixed I will have to stick with my own implementation which isn't as clean or responsive as this package.

[letsar]

Thanks, published in v0.3.0

[Wood-Water-Peng]

It's really helpful,I have fixed this problem with overriding the hitTestChildren method。
Thank you!
ps: StaggerGridView inside NestedScrollView

[mickykebe]

This solution no longer works since flutter version 1.7.

[rajesh-kc]

Upgraded flutter to 1.7 v, Now flutter_staggered_grid_view package is throwing this error "Unhandled Exception: type 'SliverHitTestResult' is not a subtype of type 'BoxHitTestResult'"

Upgraded package to 0.3.0 from 0.2.7, The error remains the same.

Requesting the author to provide a solution.

[miguelangarano]

@dereklakin 's solution works like a charm for me in Flutter 1.7.8+hotfix.3 and last updated Staggered package

[udit-wynk]

facing the same issue with Flutter 1.7.8+hotfix.3 and flutter_staggered_grid_view 0.3.0.
Please provide with a fix..

[sinuraya]

here is work for me:

1. uprgade flutter_staggered_grid_view to 0.3.0
2. if the problem still persist, delete ~/.pub-cache/hosted/pub.dartlang.org folder
3. run $ flutter pub get
4. your flutter_staggered_grid_view should work by now

[xhidnoda]

After upgrade to 0.3.0 on Flutter 1.7.8. Running flutter clean works for me.

[nixoncode]
