Hello, I would like to ask for your help regarding the issue I am experiencing using PageView on FlutterFlow.
Problem situation:
- Using FlutterFlow, we are implementing a multi-page PageView.
- PageView's Initial Page is set to 0.
- The data received by API calls from the previous page is placed in a variable called routefeedbackList and is being delivered as a parameter to the current page.
- The data is normally assigned to the routefeedbackList, and the list length is set correctly. However, a RangeError occurs when you turn PageView over.
Error message:
```
RangeError(index): Index out of range: index should be less than 1: 1
```
- An error occurs outside the index range, especially on the first (index 0) and subsequent pages (index 2,3,4, etc.) (index 1 works fine)
Additional Questions:
- I've been told that there could be an asynchronous problem in the process where the value passed as a parameter is assigned to the Generator Variable. What can happen in the process if the value is not assigned properly before the page is built?
- What are some ways in FlutterFlow that I can check if the data is allocated normally before the page is built? Other than how to display the loading screen, I'm curious about how to make sure I get and use the data before the page is built.
- I would like to know if there are any bugs or known issues related to this in your current version of FlutterFlow.
Any help would be appreciated!
