Not parsing data on startup

[spacie2136]

Hi,
first of all let me say i never used flutter nor dart. So im still lost in your code (well written btw.!).

I managed to set up everything but the app hangs on startup with this message:

I/flutter (30368): type 'String' is not a subtype of type 'Map<String, dynamic>'
E/flutter (30368): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Null check operator used on a null value
E/flutter (30368): #0 categoryProvider.. (package:Tiwee/business_logic/provider/categoryprovider.dart:23:39)

Im not sure, but it seems to me there is a mismatch in the JSON format from the pulled API and the internal objects!? (Absolutly not sure!)
I placed a try block over the for loop (just for testing) and managed to get the app running. But without any channels :-(

I'll be digging into it, but im still very lost as i said ;-) Do you maybe have an easy solution for this issue?

I'm currently investigating as well. For me, it looks like the countries are providing only one country which means it fails there.

Apparently, this app uses an older API version that is not online anymore. Many Endpoints have changed, and the app could be rewritten.

Hello, @spacie2136 @Z0pyrus sorry for the late response... this error is from APi as I used free API sometimes it does not respond correctly and returns empty data,
as I find some free time I will refactor the code to handle errors better than past,
meanwhile, ill appreciate any pull request from the community
