研究方向
The issue requests adding a method to check if the WebView can go back, similar to native Android's `canGoBack()` and iOS's `canGoBack`. To implement, you would need to add a method channel call in the Dart side and handle it in both Android (Java/Kotlin) and iOS (Swift/ObjC) native code. The existing plugin code is at https://github.com/fluttercommunity/flutter webview plugin. Look at the `flutter webview plugin.dart` and the native implementations in `android/src/main/java/` and `ios/Classes/`. The comments on the issue may provide additional context or design preferences.
