I want to have a multiple lines TextField without suggestions or autocorrect. The use case is for a writing game application.

Ios work just fine using :
keyboardType: TextInputType.multiline, enableSuggestions: false, autocorrect: false
But in an android device I still have the suggestions.

In Android natif you can achieve this using the combination of inputTypes :
android:inputType="textFilter|textMultiLine|textNoSuggestions"
But with flutter I can. only pass one argument
keyboardType: TextInputType.multiline
