confirm method

Future<bool> confirm(String message, { bool defaultValue = false, })

Asks a y/n question and returns the boolean answer.

Enter submits the current default. Pressing y/n (case-insensitive) submits immediately.

Implementation

Future<bool> confirm(
  String message, {
  bool defaultValue = false,
}) {
  bool? pending;
  var submitted = false;

  return runOneShot<bool>(
    (ctx, submit) {
      if (submitted) {
        _drawCompactAnswer(ctx, message, pending! ? 'Yes' : 'No');
        submit(pending!);
        return;
      }
      ctx.draw(
        Confirm(
          id: Key.symbol(#__inline_confirm),
          message: message,
          defaultValue: defaultValue,
          onSubmit: (v) {
            pending = v;
            submitted = true;
          },
        ),
        Rect(ctx.area.x, ctx.area.y, ctx.area.width, 1),
      );
    },
    theme: _theme,
    terminal: _terminal(),
    allowNonInteractive: _allowNonInteractive,
  );
}
