One solution would be to use a state variable in a Stateful Widget:

bool _done = false;

Listen to the edited text:

TextField(
 onChanged(s) {
   if (s.substring(s.length - 2) == "\n\n") setState(() => _done = true);
   else setState(() => _done = false);
 }
)

And change the TextInputAction accordingly:

TextField(
 onChanged(s) {
   if (s.substring(s.length - 2) == "\n\n") setState(() => _done = true);
   else setState(() => _done = false);
 },
 textInputAction: _done ? TextInputAction.done : TextInputAction.newLine
)
