MissingPluginException almost always means the native side of a plugin was added but the app binary running on the device doesn't include it yet. Hot reload is not enough — the native layer needs a full rebuild.
The Error
MissingPluginException(No implementation found for method X on channel Y)
Fix 1: Full Stop and Rebuild (Not Hot Reload)
flutter clean
flutter pub get
flutter run # a fresh build, not hot reloadAdding a plugin changes native code; you must fully stop the app and run again so the new native registration is compiled in.
Fix 2: Check Platform Support
Some plugins don't implement every platform (e.g. web or desktop). Verify the plugin lists your target platform and that you're not calling it on an unsupported one.
Fix 3: iOS Pods
cd ios && pod install && cd ..
flutter runSolution
90% of MissingPluginException reports are solved by flutter clean + full restart. Try that before anything else.
