Environment

Technology	Version
Flutter version	3.0.1
Plugin version	5.4.3+7
Android version	5 and 6

Device information:

Description

Spected behavior: Use flutter_inappwebview package on Android 5 and 6 devices in conjunction with other packages that load dynamic libraries (specifically Isar, flutter_js).

Current behavior: It is not possible to load the dynamic libraries of the other packages, when using the flutter_inappwebview package(on Android 5 and 6).

Steps to reproduce

1. Add this to your pubspect.yaml in a new project:

 ...
 flutter_js: ^0.5.0+6
 isar: ^3.0.0-dev.0
 flutter_inappwebview: ^5.4.3+7

2. Try on an emulator or physical device running Android 5 or 6. You will get an error like this:

Unable to load dynamic library  *.so

3.Now do the same but without the inappwebview flutter package:

 ...
 flutter_js: ^0.5.0+6
 isar: ^3.0.0-dev.0

4. Everything will load correctly.

Note.- on devices with Android >= 7, it works correctly. The problem appears only on devices with Android 5 and 6 (SDK <=22)

Stacktrace/Logcat

So the problem is from flutter inappwebview

Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!
