webview_flutter_linux #

An experimental, non-endorsed Linux implementation of Flutter's official webview_flutter plugin. It uses the WPE WebKit runtime installed on the host and renders web content into a Flutter texture without embedding a GTK browser widget or bundling a browser engine.

Add the official plugin and this Linux implementation to a Flutter app:

dependencies:
  webview_flutter: ^4.14.1
  webview_flutter_linux: ^0.1.0-dev.2

Usage #

Use the standard webview_flutter API:

import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';

final controller = WebViewController()
  ..setJavaScriptMode(JavaScriptMode.unrestricted)
  ..loadRequest(Uri.parse('https://flutter.cn'));

class BrowserView extends StatelessWidget {
  const BrowserView({super.key});

  @override
  Widget build(BuildContext context) {
    return WebViewWidget(controller: controller);
  }
}

See example/lib/main.dart for a complete example.

Linux runtime requirements #

The native asset contains the Rust bridge, but it does not bundle a browser engine. The target system must provide WPE WebKit 2.52 or newer, built with WPE Platform support. Install the distribution package that provides libWPEWebKit-2.0.so.1; its dependency resolver should also install the WPE backend and the libraries used directly by the bridge:

• libepoxy (libepoxy.so.0)
• libsoup 3 (libsoup-3.0.so.0)
• GLib, GObject, and GIO
• ATK accessibility support (libatk-1.0.so.0)

For example:

# Arch Linux
sudo pacman -S wpewebkit

# Debian testing/unstable, when the repository provides WPE WebKit 2.52+
sudo apt install libwpewebkit-2.0-1

# Fedora, from a repository that provides WPE WebKit 2.52+
sudo dnf install wpewebkit

Older distribution releases may only provide an incompatible WPE WebKit version. Confirm that both wpe-webkit-2.0 and wpe-platform-2.0 report 2.52 or newer when their pkg-config files are installed:

pkg-config --modversion wpe-webkit-2.0 wpe-platform-2.0

Git and path dependencies compile the Rust bridge locally and additionally require the development packages for WPE WebKit, libepoxy, and ATK, plus pkg-config. Published package releases use the prebuilt bridge and require only the runtime libraries.

Audio and video format support comes from the host's GStreamer plugins. Install the appropriate base, good, bad, ugly, and libav plugin packages for the media formats the application needs.
