IsMap': is not a member of 'flutter::EncodableValue

[Falamarcao]

Issue: I can't build using current Flutter dev channel version so I would like to know which Flutter's version your plugin can run successfully.

Flutter doctor output:

Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel dev, 1.27.0-4.0.pre, on Microsoft Windows [Version 10.0.19042.804], locale en-G
B)
[√] Android toolchain - develop for Android devices (Android SDK version 30.0.2)
[√] Chrome - develop for the web
[√] Visual Studio - develop for Windows (Visual Studio Community 2019 16.6.2)
[√] Android Studio (version 4.1.0)
[√] IntelliJ IDEA Community Edition (version 2019.3)
[√] Connected device (3 available)

On current version I'm encountering these exceptions:
