Kotlin Experimental Feature Issue

[ebitogu]

Hello, thanks for the time taken to make this amazing library.

However, I couldn't get it to work.

This is what I keep getting:

e: C:\flutter\.pub-cache\hosted\pub.dartlang.org\fluttercontactpicker-4.5.0\android\src\main\kotlin\me\schlaubi\fluttercontactpicker\ContactPicker.kt: (22, 115): This declaration is experimental and its usage must be marked with '@kotlin.ExperimentalStdlibApi' or '@OptIn(kotlin.ExperimentalStdlibApi::class)'

I can't reporduce this with flutter build can you tell me which command you used

[DRSchlaubi]

Fixed in 4.5.1

[DRSchlaubi]

Whoops wrong issue

[ebitogu]

I used this command

flutter run lib/main.dart --no-sound-null-safety

Here is my android config

defaultConfig{
 minSdkVersion 20
 targetSdkVersion 30
}

I have the same breaking issue, downgrading to 4.4.0 and flutter clean fixed it for me:

  fluttercontactpicker: 4.4.0

  fluttercontactpicker: 4.4.0

But 4.4.0 is not supported anymore and shouldn't be used

My guess is that you havea kotlin version before 1.5 in your app in which that function is marked as experimental so make sure to use kotlin 1.5 as well

Thanks for your feedback!

Indeed my previous kotlin-version was 1.4.31 in android/build.gradle, upgrading to 1.5.0 fixed the problem.

buildscript {
    ext.kotlin_version = '1.5.0'
   [...]
}

Currently the fluttercontractpicker documentation states: "Note: This plugin requires at least Kotlin 1.4.0 to compile". It would be nice to update this requirement and also specify how to do it.

Thanks @DRSchlaubi, increasing my kotlin version to 1.5 fixed it.
