Why can't I create a TextField?

Question

Dart

return Scaffold(
      backgroundColor: color_grey,
      body: SafeArea(
        child: Row(
          children: [
            TextField(
                obscureText: true,
                cursorColor: color_red,
                decoration: InputDecoration(
                  enabledBorder: OutlineInputBorder(borderRadius: BorderRadius.circular(5), borderSide: BorderSide(color: Colors.grey)),
                  focusedBorder: OutlineInputBorder(borderRadius: BorderRadius.circular(5), borderSide: BorderSide(color: color_red, width: 2))
                )
                
            ),
          ],
        ),
      )
      );

The studio automatically transfers me to

static _doThrowNew(int assertionStart, int assertionEnd, Object? message)
      native "AssertionError_throwNew";

in the errors_patch.dart file
I want to clarify that this only happens with TextField
