evalJavascript(document.documentElement.innerHTML) escaped text? #417

The response is JSON escaped, so if anyone else runs into this problem, just use the built in decode function in the dart-convert package to unescape it.

I'm trying to get the source from a webview, and I'm using evalJavascript to try and get the document's innerHTML:
@override void initState() { flutterWebviewPlugin.onStateChanged.listen((state) async { if (state.type == WebViewState.finishLoad) { String response = await flutterWebviewPlugin.evalJavascript('document.documentElement.innerHTML;'); print(response); } }); }But the output is always some form of escaped text:
"\u003Chead>\u003Cmeta charset=\"UTF-8\">\u003Cmeta content=\"width=device-width,minimum-scale=1.0\" name=\"viewport\">\u003Cmeta content=\"telephone=no\" name=\"format-detection\">\u003Cmeta content=\"address=no\" name=\"format-detection\">\u003Cmeta content=\"origin\" name=\"referrer\">\u003Cmeta content=\"notranslate\" name=\"google\">\u003Clink href=\"/images/branding/product/1x/gsa_android_144dp.png\" rel=\"icon\">\u003Cmeta content=\"/images/branding/googleg/1x/googleg_standard_color_128dp.png\" itemprop=\"image\">Is this the proper behavior? I can't seem to figure out what type of escape this is. One of the things I was thinking is if there was a way to catch it earlier? I noticed that if I use console.log, it seems to output in the flutter console in proper formatting:
String response = await flutterWebviewPlugin.evalJavascript('console.log(document.documentElement.innerHTML);');Which yields something like this:
[INFO:CONSOLE(1)] "<head><meta charset="UTF-8"><meta content="width=device-width,minimum-scale=1.0" name="viewport"><meta content="telephone=no" name="format-detection"><meta content="address=no" name="format-detection"><meta content="origin" name="referrer"><meta content="notranslate" name="google"><link href="/images/branding/product/1x/gsa_android_144dp.png" rel="icon"><meta content="/images/branding/googleg/1x/googleg_standard_color_128dp.png" itemprop="image"><title>Google</title><script nonce="vnS8R6Yzt54tLKduMnYLPg==">The text was updated successfully, but these errors were encountered:
