It seems GlobalMaterialLocalizations.delegate does not support the zh Locale (Chinese).
Is it really necessary adding GlobalCupertinoLocalizations.delegate before other locales works?
I get this error each time I run the app without adding the GlobalCupertinoLocalizations delegate:
Could this be a bug in Flutter? because according to the official Docs HERE the GlobalMaterialLocalizations.delegate does have support for zh - Chinese
