Remove references to deprecated v1 Android embedding

[reidbaker]

Use case

Apps can use your code when updating to future versions of flutter.

Proposal

To ensure this plugin will work with users running the next stable version of Flutter remove references to the v1 embedding.

The v1 embedding was deprecated around 6 and a half years ago. In Flutter 3.22, the Flutter tool dropped support for building v1 apps entirely. Flutter plans to delete version one of it's Android embedding in the next stable release, per https://medium.com/flutter/whats-new-in-flutter-3-22-fbde6c164fe3 (in the "Removal of v1 Android embedding" section).

When that deletion happens, any apps using plugins that still have references to the removed classes will fail to build when updating to the next stable version (probably Flutter 3.26).

As a part of this deprecation, the Flutter Android team is doing community outreach by filing bugs and submitting some pull requests to update plugins to minimize the impact this removal has on the community.

Some example PRs:

• Flutter team maintained plugins: [many] Remove references to v1 embedding flutter/packages#6494
• android_alarm_manager_plus fix(android_alarm_manager_plus): Remove references to v1 embedding fluttercommunity/plus_plugins#2864

Consequences:

• This change should have no impact on users of this plugin that are building apps using the v2 embedding (we don't have a percentage to share, but this is the vast majority of users).
• It will remove support for users that are still using the v1 embedding on version of Flutter older than 3.22.

If this change doesn't land, this plugin will instead be broken for all apps building on the next stable version of Flutter and beyond.

Is there a way to support both v1 and v2 embedding apps in the next stable version of Flutter?

No.

This is the PR where we are removing the deprecated engine classes: flutter/engine#52022

Hi @reidbaker,
Thank you very much for informing us about the upcoming changes in Flutter that will affect our plugin and for your proactive approach in filing the issue and submitting a patch.

We will review the patch and consider making the necessary changes to our source as soon as possible to ensure our users remain supported with the next Flutter version.

@reidbaker We have removed the references to deprecated v1 Android embedding from the syncfusion_flutter_pdfviewer source and these changes are included in version 27.1.48. So, we are closing this as completed

Confirmed I see no more references. Thank you!
