Marionette for Flutter

Marionette is a library which provides a high-level API to control a WebView.

The goal is to have the API closely mirror that of Puppeteer.

Other platforms: Swift (macOS/iOS), JavaScript (Node)

Usage

import 'package:flutter_marionette/marionette.dart';

() async {
  final page = Marionette();

  await page.goto("https://www.google.com/");
  await page.type("input[name='q']", "LinusU Marionette")
  await Future.wait([page.waitForNavigation(), page.click("input[type='submit']")]);

  page.dispose();
}

iOS

To be able to use Marionette on iOS, you need to give Marionette a hook to your view hierarchy. Otherwise the WKWebView will get suspended by the OS, and your Promises will never settle.

This is accomplished by using the setGlobalUIHook function before instantiating any Marionette instances.

Flutter:

If you have a non-modified Flutter application, this should be added to ios/Runner/AppDelegate.swift, in the application(_:didFinishLaunchingWithOptions:) function.
