Hi everyone, please can you help me out with this issue...
i am finding it difficult retrieving data from Firestore using StremBuilder. it retrieves data once and stops working then brings up the following error...

A RenderViewport expected a child of type RenderSliver but received a child of type RenderErrorBox.

RenderObjects expect specific types of children because they coordinate with their children during layout and paint. For example, a RenderSliver cannot be the child of a RenderBox because a RenderSliver does not understand the RenderBox layout protocol.
The RenderViewport that expected a RenderSliver child was created by: Viewport ← IgnorePointer-[GlobalKey#a5fd6] ← Semantics ← Listener ← _GestureSemantics ← RawGestureDetector-[LabeledGlobalKey#a0a2b] ← Listener ← _ScrollableScope ← _ScrollSemantics-[GlobalKey#eedc1] ← NotificationListener ← RepaintBoundary ← CustomPaint ← ⋯
The RenderErrorBox that did not match the expected child type was created by: ErrorWidget-[#a5df3] ← StreamBuilder<QuerySnapshot<Object?>> ← Viewport ← IgnorePointer-[GlobalKey#a5fd6] ← Semantics ← Listener ← _GestureSemantics ← RawGestureDetector-[LabeledGlobalKey#a0a2b] ← Listener ← _ScrollableScope ← _ScrollSemantics-[GlobalKey#eedc1] ← NotificationListener ← ⋯
The relevant error-causing widget was:

Please see this StackOverflow answer if it can help.

Also, the goal of this Github repo is not to give assistance on personal code or the whole package/plugin project, but to improve Flutter framework reporting bugs or feature requests.

If you encounter behavior that you believe could be a bug, please provide a completed and minimal reproducible code sample that represents the problem. Also, please provide the output of flutter doctor -v as well.

Instead, if you think that the issue might depend on your implementation, please see flutter's community for resources and ask questions like this. You may also get some help if you post it on Stack Overflow and flutterhelp.

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
