Steps to Reproduce

Just run any application using flutter_webview_plugin version 0.4.0 after upgrading to Flutter 2.5 and you will get the warning message.

Logs

The plugin `flutter_webview_plugin` uses a deprecated version of the
Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see
if this plugin supports the Android V2 embedding. Otherwise, consider
removing it since a future release of Flutter will remove these deprecated
APIs.
If you are plugin author, take a look at the docs for migrating the plugin
to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

I can Confirm this solved my problem on flutter 3.

[RoarGronmo]

Nope... i got this error trying your solution @hawkiq

Because aad_oauth 0.3.0 depends on flutter_webview_plugin ^0.4.0 and no versions of aad_oauth match >0.3.0 <0.4.0, aad_oauth ^0.3.0 requires flutter_webview_plugin from hosted.
So, because mwork depends on both aad_oauth ^0.3.0 and flutter_webview_plugin from git, version solving failed.
pub get failed (1; So, because mwork depends on both aad_oauth ^0.3.0 and flutter_webview_plugin from git, version solving failed.)

because you use this package aad_oauthwhich depends on flutter_webview_pluginolder version so maybe your problem will stay until resolved by package maintainers, for me I've updated flutter_webview_plugin to use git source https://github.com/nuc134r/flutter_webview_plugin.git and my app can be built again.

Careful to keep using the webview_plugin even with the nuc134r version in newer flutter project. It will break the Android version

In pubspec.yaml instead of writing version number try to write it as they mention

I recommend use webview_flutter plugin instead of this abandoned project.
