[Bug]: Error: zego_express_engine-3.19.0 - cannot find symbol import io.flutter.plugin.common.PluginRegistry.Registrar;

[digarahayu]

After updating Flutter to version 3.29, the zego_express_engine library (version 3.19.0) fails to build due to a breaking change in the Flutter API. Specifically, the issue is related to the use of the now-removed Registrar class from the io.flutter.plugin.common.PluginRegistry package.

Here is the error message:
error: cannot find symbol
import io.flutter.plugin.common.PluginRegistry.Registrar;
^ symbol: class Registrar
location: interface PluginRegistry

This issue occurs because the Registrar API has been removed in recent versions of Flutter, and the library needs to be updated to use the FlutterPlugin API instead.
