A Flutter plugin that allows you to add an inline WebView.

native_webview

A Flutter plugin that allows you to add an inline WebView.

Motivation

There is already a useful library for working with WebViews in Flutter.

These libraries come with trade-offs such as simple implementation but lack features, or very advanced features and complex implementation.

native_webview is designed to provide users with a standard set of WebView features provided by iOS and Android while keeping the implementation simple.

Developers Preview Status

The native_webview is dependent on the PlatformView. Since this PlatformView is currently in the Developer Preview, this plugin should also be considered a Developer Preview. Known issues are tagged with the flutter/flutter’s platform-views label.

If you want to run native_webview on iOS, please test it on an actual device such as an iPhone.
