Installation

Add the app-facing package:

dependencies:
  webview_all: ^1.2.0

Run:

flutter pub get

The main package registers platform implementations through Flutter’s federated plugin mechanism:

flutter:
  plugin:
    platforms:
      android:
        default_package: webview_flutter_android
      ios:
        default_package: webview_flutter_wkwebview
      macos:
        default_package: webview_flutter_wkwebview
      linux:
        default_package: webview_all_linux
      windows:
        default_package: webview_all_windows
      ohos:
        default_package: webview_all_ohos
      web:
        default_package: webview_all_web

When to Add Platform Packages Directly

If your app only uses the common API, webview_all is enough.

If you cast to a platform implementation, add that package explicitly so the import is available to your app:

dependencies:
  webview_all: ^1.2.0
  webview_all_windows: ^1.2.0
  webview_all_linux: ^1.2.0
  webview_all_ohos: ^1.2.0
  webview_all_web: ^1.2.0
  webview_flutter_android: ^4.12.0
  webview_flutter_wkwebview: ^3.25.0

Then import only the packages you need:

import 'package:webview_all/webview_all.dart';
import 'package:webview_all_windows/webview_all_windows.dart';
import 'package:webview_all_linux/webview_all_linux.dart';
import 'package:webview_all_ohos/webview_all_ohos.dart';
import 'package:webview_all_web/webview_all_web.dart';
import 'package:webview_flutter_android/webview_flutter_android.dart';
import 'package:webview_flutter_wkwebview/webview_flutter_wkwebview.dart';

Version Contract

The 1.2.0 release is aligned across all webview_all_* platform packages. The wrapper depends on webview_flutter_platform_interface ^2.15.1, webview_flutter_android ^4.12.0, and webview_flutter_wkwebview ^3.25.0.

Keep the platform packages on the same minor line as the wrapper unless you are intentionally testing a platform package in isolation.
