mintware-de / flutter_p2p Goto Github PK

Hey!! I am getting this error and can't find my way around it. I did go through StackOverflow but the fixes didn't work for me. I have upgraded all versions as per the recommendation as well.

FAILURE: Build failed with an exception.

• What went wrong:
  The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.10 and higher.
  The following dependencies do not satisfy the required version:
  project ':flutter_p2p' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.71

This seems like a pretty cool project!

I am not very familiar with WiFi Direct, but my understanding was that Apple does not support it (as in: it will not be possible to communicate between iOS and Android using this plugin). Is that correct?

Iam getting this error when i run my first flutter app in Android studio using FLutter run command, Please help me

Shown below are the errors when i run "Flutter run -v"

flutter verion is
➜ example dart --version
Dart VM version: 2.8.2 (stable) (Mon May 11 15:06:42 2020 +0200) on "macos_x64"
➜ example

The example given on the package page does not match the example code mentioned in the repository.
The example on the pub.dev page doesn't work either. It should be updated to reflect the latest, working example.

I tried to integrate the plugin for a personal project, but at first I had a version problem. So I tried to update the flutter project and then it does the build. But when I launch it I get no action in return, it detects the wifi and then nothing. Please help me
