We fixed it by keeping, 23.2.4 version without carrot symbol, so it will not upgrade.

syncfusion_flutter_datepicker: 23.2.4

You should upgrade Flutter SDK to the latest version and resolve this issue. @pen110

Hi,

We have analyzed your query and checked the reported issue. We would like to inform you that the textScaleFactor property has been deprecated to the textScaler property from Flutter 3.16.0. Our packages are now compatible with the 3.16 version. To resolve the mentioned issue regarding "The getter 'textScaler' isn't defined for the 'MediaQueryData'", we suggest upgrading the Flutter SDK to the latest version.

Regards, Lokesh P.

Hi @marah126,

We have checked the reported issue by implementing a simple sample using the mentioned version of the Flutter SDK, and unfortunately, we are unable to replicate the mentioned issue.

However, we suspect that the mentioned issue might have occurred due to some cache, and we recommend that you check by clearing the cache using the below-mentioned methods:

  1. In the Flutter terminal, add the "flutter pub cache clean" command to clear all the cache.
  2. Close the running application and then add the "flutter clean" command.
  3. Afterwards, add the "flutter pub get" command to get all the dependencies in the pubspec.yaml file.

If you still face the mentioned issue even after clearing the cache, then kindly share with us some detailed information regarding the issue, along with any snapshots or recordings. With that additional information, it will be very useful for us to find a possible solution from our end.

If you have further queries, please get back to us.

Regards,

Preethika Selvam.
