Showing Error While loading post from Firebase Cloud.. I am using provider in my Application
setState() or markNeedsBuild() called during build.
Detailed Error
════════ Exception caught by foundation library ════════════════════════════════
The following assertion was thrown while dispatching notifications for PostFunctions:
setState() or markNeedsBuild() called during build.
This _InheritedProviderScope<PostFunctions> widget cannot be marked as needing to build because the framework is already in the process of building widgets. A widget can be marked as needing to be built during the build phase only if one of its ancestors is currently building. This exception is allowed because the framework builds parent widgets before children, which means a dirty descendant will always be built. Otherwise, the framework might not visit this widget during this build phase.
My Code When I Load Post..
Widget feedBody(BuildContext context) {
return SingleChildScrollView(
child: Padding(
padding: const EdgeInsets.only(top: 8.0),
child: Container(
child: StreamBuilder<QuerySnapshot>(
stream: FirebaseFirestore.instance
.collection('posts')
.orderBy('time', descending: true)
.snapshots(),
builder: (context, snapshot) {
if (snapshot.connectionState == ConnectionState.waiting) {
return Center(
child: SizedBox(
height: 200.0,
width: 200.0,
child: Lottie.asset('assets/animations/loading.json'),
),
);
} else {
return loadPosts(context, snapshot);
}
},
),
height: MediaQuery.of(context).size.height * 0.80,
width: MediaQuery.of(context).size.width,
