LateInitializationError occurs when used in isolate about libsodium_dart_bindings HOT 1 CLOSED

SodiumPlatform.instance is initialized automatically by flutter when the plugin is loaded. This happens as part of the WidgetsBinding.ensureInitialized() in normal code. This is not automatically executed when launching a new isolate, thus it does not get initialized. It did work with older versions, as back then flutter did not support loading dart plugins automatically.

This is not a bug, but expected behaviour. You have to do one of the following things to use the plugin in a different isolate:

1. Simply call WidgetsBinding.ensureInitialized() in your Isolate
2. Use a plugin like flutter_isolate that takes care of that for you.
3. Manually initialize the instance. This requires you to now which platform you are on and select the correct implementation. See https://github.com/Skycoder42/libsodium_dart_bindings/tree/main/packages/sodium_libs/lib/src/platforms where you can find the concrete implementations. For example, to initialize it for Android, you could call SodiumAndroid.registerWith().
