Project title:
Flutter Method Channel Bug – 1-Day Fix for Senior Dev
Posted by:
External project from PeoplePerHour
Started:
09-Jun-2025 07:00 GMT
Description:
PLEASE NOTE:
1. you must have xcode 14 due to the code is so old, check this first before you bid or respond.
2. you must have iphone X/10 or newer but not iphone 16 and you cannot run simulator with this software (too much to explain here)
3. The accepting developer had an old MAC with xcode 14 and it is still not installing and running the code, that is why it is posted again.

UPSIDE: if you can do this fast we need to upgrade the code for the app aftervthe bugs are done

I have a fully working Flutter app that calls a backend API delivering a dataset across 14 areas. All data is successfully received by Flutter. However, 4 of the 14 areas are not forwarded from Flutter to the native layer.

I suspect this is a format of the data in th methodchannel. That was the issue at another point.

Backend: working
Native modules (iOS + Android): confirmed solid (stable for 2+ years)
Flutter → MethodChannel: failing to pass 4 specific areas (10 areas work fine)

The Issue
- Flutter receives all 14 areas from the API
- Only 10 areas are passed to the native layer via MethodChannel
- The 4 missing areas are not reaching native, even though structure/format is the same
- This is likely a minor Dart-side formatting or dispatch issue

Your Task
- Investigate the Dart → MethodChannel logic
- Confirm the 4 failing areas are properly forwarded
- Validate they reach iOS (Swift) and Android (Java/Kotlin)
- Fix any Dart-side bugs or mismatches
- Keep everything else untouched — the app works well overall

Requirements
- Senior-level Flutter experience
- Deep knowledge of MethodChannel (both iOS and Android sides)
- Experience with native integration debugging
- Mac with iOS build support (state your Mac model)
- Can clone, run, test app end-to-end

To Apply
Please reply with:
1. Mac model (e.g., MacBook Pro M2, Sonoma)
2. Years of experience in Flutter + Native (iOS & Android)
3. Your MethodChannel experience (examples welcome)
4. Availability (ready to start = great)

This is a micro-engagement (1-day task) — ideal for a senior dev who knows native-flutter bridges cold.
