<p dir="auto">Hi.<br>
How do I create a TextArea? That means a TextField where when you press enter on your keyboard it adds a new line, something like notepad, or really any text editor. When I press enter in a TextField it just toggles the keyboard.<br>
How can I achieve this in flutter? Thank you.</p>
