ios – Flutter overlays (Dialog, BottomSheet, ..etc) close immediately after opening on iPadOS 26.1

This is a known issue in Flutter — see the GitHub issue here:
🔗 flutter/flutter#177992

It happens on iPadOS 26.1 when showing a dialog, bottom sheet, or end drawer with barrierDismissible: true.

✅ Temporary workaround:

You can manually control the outside-tap behavior using a TapRegion and ignore taps that happen too quickly after opening the dialog.

Here’s the workaround from the Flutter GitHub issue comments:
🔗 flutter/flutter#177992 (comment)

final now = DateTime.now();
return showDialog(
  context: context,
  barrierDismissible: false,
  builder: (BuildContext context) {
    return TapRegion(
      onTapOutside: (_) {
        // Workaround for 
        if (DateTime.now().difference(now) < Duration(milliseconds: 500)) {
          return;
        }
        if (Navigator.canPop(context)) {
          Navigator.pop(context);
        }
      },
      child: ... // your dialog content
    );
  },
);

This prevents the dialog or drawer from closing immediately due to an unintended outside tap event on iPadOS 26.1.
