Creating such an editor can be very complicated. The principle is easy, though. Create a notifier that holds your models, observe that notifier and draw the objects accordingly to the models, then modify the model based on the UI interaction.

Here's a model:

class Box {
  Box({
    required this.center,
    required this.size,
    required this.rotation,

required this.color,

I want to support indentation in a multiline TextField.

What's the best way to do so? Here's my current approach.

To indent on TAB, I use an explicit TextEditingController and wrap the TextField in a CallbackShortcuts widget to detect the TAB key. I know I could use intents and actions here, but it's simpler this way. I can access then controller from the callbacks.

class _Editor extends State<Editor> {
  final _controller = TextEditingController();

I wrote

/// Parses [input] as an .ini configuration.
Map<String, Map<String, String>> 

and Copilot completed this:

/// Parses [input] as an .ini configuration.
Map<String, Map<String, String>> parse(String input) {

final result = >{};
