How can I solve the issue of set state () or markneedsbuild () during UI rendering?
When I was engaging with the development of a flutter-based application, I encountered an error message of “setstate() or markneedsbuild () called during build”. How can k solve this particular issue for seamless UI rendering?
In the context of mobile development, if you are getting the issue of “setstate() or markneedsbuild()”, then you should follow the following steps for troubleshooting your particular issue:-
Identify the trigger points
First, identify the trigger points within your widget tree. It could be within the q method which is invoked during the process of building.
Separate UI updates
Ensure that any changes which are triggering UI updates by using “set state” should be called after the building process is done not during the process.
Here is the example given to showcase:
@override
Void initState() {
Super.initState();
WidgetsBinding.instance.addPostFrameCallback((_) {
// Call setState() or markNeedsBuild() here after the build cycle
setState(() {
// Update state variables or UI components
});
});
}
