Flutter - Textfield add new line

Question

I try to make a TextField with keyboardType: TextInputType.visiblePassword to disable the predictive text but with that I can't go to a new line because it's a submit button. I try to add textInputAction: TextInputAction.newline but don't work too.

My TextField:

TextField(
     focusNode: myFocusNode,
     autocorrect: false,
     enableSuggestions: false,
     toolbarOptions: ToolbarOptions(copy: false, cut: false, paste: false),
     keyboardType: TextInputType.visiblePassword,
     textInputAction: TextInputAction.newline,
     autofocus: true,
     maxLines: null,
     controller: textEditor,
     decoration: InputDecoration(fillColor: Colors.grey[100])
))));

Answer 1

You just add below parameter to disable predicting text.

enableSuggestions: false,
autocorrect: false,

But to enable multiline, you need to change 'keyboardType' to 'TextInputType.multiline'.

TextField(
        autocorrect: false,
        enableSuggestions: false,
        toolbarOptions: ToolbarOptions(copy: false, cut: false, paste: false),
        keyboardType: TextInputType.multiline,
        textInputAction: TextInputAction.newline,
        autofocus: true,
        maxLines: null,
        decoration: InputDecoration(fillColor: Colors.grey[100]))
