A new Flutter project.
## Getting Started
This project is a starting point for a Flutter application.
A few resources to get you started if this is your first Flutter project:
- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
For help getting started with Flutter development, view the
[online documentation](https://docs.flutter.dev/), which offers tutorials,
samples, guidance on mobile development, and a full API reference.

# webview_windows
[![CI](https://github.com/jnschulze/flutter-webview-windows/actions/workflows/ci.yml/badge.svg)](https://github.com/jnschulze/flutter-webview-windows/actions/workflows/ci.yml)
[![Pub](https://img.shields.io/pub/v/webview_windows.svg)](https://pub.dartlang.org/packages/webview_windows)
A [Flutter](https://flutter.dev/) WebView plugin for Windows built on [Microsoft Edge WebView2](https://docs.microsoft.com/en-us/microsoft-edge/webview2/).
### Target platform requirements
- [WebView2 Runtime](https://developer.microsoft.com/en-us/microsoft-edge/webview2/)
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](https://developer.microsoft.com/en-us/microsoft-edge/webview2/).
- 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)*
## Demo
![image](https://user-images.githubusercontent.com/720469/116823636-d8b9fe00-ab85-11eb-9f91-b7bc819615ed.png)
https://user-images.githubusercontent.com/720469/116716747-66f08180-a9d8-11eb-86ca-63ad5c24f07b.mp4
## Limitations
This plugin provides seamless composition of web-based contents with other Flutter widgets by rendering off-screen.
Unfortunately, [Microsoft Edge WebView2](https://docs.microsoft.com/en-us/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.
