Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

A Flutter package that provides a WebView2-powered web view implementation for Windows, enabling seamless integration of web content within desktop applications. Built specifically for the Windows platform, it leverages Microsoft's WebView2 control, which is based on Chromium, ensuring modern web compatibility and performance. The package allows developers to display web pages, handle navigation, and interact with JavaScript from Dart. It supports common web view features like URL loading, navigation events, and basic scripting. Ideal for embedding web-based UIs or content in Windows desktop apps built with Flutter.

Use cases

Embedding web content in Windows desktop apps
Displaying dynamic web-based interfaces
Integrating web services into desktop applications
Building hybrid desktop applications with web components
Creating rich user experiences with embedded web views

Key features

Chromium-based web engine
JavaScript interaction support
Navigation event handling
Cross-platform compatible with Flutter desktop

Suitable for

Flutter developers targeting Windows desktop
Apps requiring embedded web content
Hybrid desktop applications with web components
Developers needing modern web rendering on Windows
Projects using WebView2 for Windows-specific functionality

Considerations

A Flutter WebView plugin for Windows built on Microsoft Edge WebView2.

Target platform requirements

WebView2 Runtime
Before initializing the webview, call getWebViewVersion() to check whether the required WebView2 Runtime is installed or not on the current system. If getWebViewVersion() returns null, guide your user to install WebView2 Runtime from this page.
Windows 10 1809+

Development platform requirements

Visual Studio 2019 or higher
Windows 11 SDK (10.0.22000.194 or higher)
(recommended) nuget.exe in your $PATH (The makefile attempts to download nuget if it's not installed, however, this fallback might not work in China)

Limitations

This plugin provides seamless composition of web-based contents with other Flutter widgets by rendering off-screen.

Unfortunately, Microsoft Edge WebView2 doesn't currently have an explicit API for offscreen rendering. In order to still be able to obtain a pixel buffer upon rendering a new frame, this plugin currently relies on the Windows.Graphics.Capture API provided by Windows 10. The downside is that older Windows versions aren't currently supported.

Older Windows versions might still be targeted by using BitBlt for the time being.
