Error: 'PointerExitEvent' isn't a type


I tried to implement the Datagrid PDF export. To do this I tried to follow the steps outlined here: https://help.syncfusion.com/flutter/datagrid/export-to-pdf 

Now, even though I have rolled back all changes before trying to implement the PDF export, the SfDataGrid will no longer allow my application to compile - it fails at compile.

The error I'm seeing is as follows:

Waiting for connection from debug service on Chrome...

../../.pub-cache/hosted/pub.dartlang.org/syncfusion_flutter_datagrid-20.3.49/lib/src/datagrid_widget/widgets/cell_widget.dart:733:23: Error: 'PointerEnterEvent' isn't a type.

            onEnter: (PointerEnterEvent details) {


../../.pub-cache/hosted/pub.dartlang.org/syncfusion_flutter_datagrid-20.3.49/lib/src/datagrid_widget/widgets/cell_widget.dart:738:22: Error: 'PointerExitEvent' isn't a type.

            onExit: (PointerExitEvent details) {


Failed to compile application.

My Pubspec.yaml file is as follows: 

  # The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^1.0.2
firebase_core: ^1.21.1
firebase_auth: ^3.7.0
cloud_firestore: ^3.4.6
syncfusion_flutter_calendar: ^20.2.40
provider: ^6.0.3
syncfusion_flutter_datagrid: ^20.3.49

sdk: flutter

Please let me know what other information might be needed to resolve this.

In case this helps, below is the screen and the widget control that are using this control.

I want to note that this was working great until the attempt at exporting the grid to PDF. Then this error started to occur and will not go away despite clearing cache, flutter clean commands and finally removing the export to PDF code.. now the SfDatagrid will not work at all and throws the error above.

I'd prefer to stay with Sf products as the Calendar is working well, but will have to shift if I can't resolve in the next couple of days.

Hi Martin,

We suspect that you are using an older version of the Flutter SDK. We are unable to reproduce the reported issue with the latest version. It’s working fine on our end. If you're using an older version, can you please upgrade your Flutter SDK version to 3.3.4 (the latest stable version) and let us know if you are still facing the same issue?

Hi Tamilarasan,

I'm on Flutter version 3.0.5 and will try this upgrade path.

It looks like upgrading to v 3.3.4 has resolved - I will continue to test and reach out if I continue to experience issues.

Thank you.
