Android versions 17 & 18 Javascript Inject Error

[ominibyte]

Hi,

First, let me start by saying well done and thanks for this plugin.

I use this plugin currently for the ability to run javascript from my flutter application. I have a JS library which I link on a bare html page. However, I noticed that there is always a console error even when I do not load my own script. It shows up when the about:blank page finishes loading as well as when my own html page stops loading. I have tested on Android versions 17 and 18 and I really would like it to work for at least Android 18. I have tested on the more recent versions of Android (like Pie) and it works so I do not know how far back it doesn't work for. I don't know what the issue may be but I would greatly appreciate any help you can provide me towards fixing this. Here is the error message from the console listener, exactly same even after loading my page:

I/flutter ( 5500): Stopped about:blank
I/flutter ( 5500):
