Flutter Method Channel Bug – 1-Day Fix for Senior Dev
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.
