build failure with latest version of flutter

[wutsi]

I've just upgraded flutter, and I received the following error

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher.
The following dependencies do not satisfy the required version:
project ':search_choices' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50

Can you update the kotlin plugin version from 1.3.50 to 1.5.20?
Thanks

Hello @wutsi , thanks a lot for letting me know.

I will reproduce the issue, update the code for correction, run the automated testing and publish the changes as soon as possible.

Hi again @wutsi ,

I was not able to reproduce this issue yet with the latest version of Flutter.

Here is the output of flutter doctor -v:

I updated the kotlin version numbers anyway from 1.3.50 to 1.7.20 with version 2.1.4 of the search_choices plugin. Waiting for the Flutster automated testing to complete successfully before publishing to pub.dev .

[lcuis]

Release 2.1.14 of search_choices was successfully automatically tested with this video and thus released to pub.dev . Thanks @wutsi for bringing this issue to my attention!
You can close this issue if you consider everything is fine. Otherwise, I will probably close it myself in a few days.

[wutsi]

I start having this issue since I've added flutter_chat_ui into my project. Let me check and re-confirm

[wutsi]

confirmed - everything is fined
Thanks

[lcuis]

Thank you very much @wutsi for the explanation and confirmation!

I'm having issues building for Android as well after upgrading to the latest flutter stable AND search_choices: ^2.1.4

Hello @samumzizi ,

Thanks for reaching out on this.

I would try to follow the recommendation on this StackOverflow answer.
Try replacing Jcenter() by mavenCentral() in the android/build.gradle.

I hope this will solve your issue.

[samumzizi]

Hi @lcuis,
I tried the solution on stack overflow and I still have the same problem.

my android/build.gradle now looks like this per the stack overflow solution:

buildscript {
ext.kotlin_version = '1.6.20'
repositories {
google()
mavenCentral()
}

dependencies {
    classpath 'com.android.tools.build:gradle:4.1.3'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.3.5'
}

}

allprojects {
repositories {
google()
mavenCentral()
}
}

rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
delete rootProject.buildDir
}

and the last part of the error I get still looks like this:
`> Failed to notify project evaluation listener.

Could not get unknown property 'android' for project ':search_choices' of type org.gradle.api.Project.
Could not get unknown property 'android' for project ':search_choices' of type org.gradle.api.Project.

Hi @samumzizi ,

Sorry for the inconvenience.

Maybe this StackoverFlow answer would be a better solution then?

In your android/build.gradle, try replacing the gradle dependency classpath by this:

classpath 'com.android.tools.build:gradle:7.0.0'

In your android/gradle/wrapper/gradle-wrapper.properties, try replacing the distribution url as follows:

distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.2-all.zip

Thanks for your help. I tried that and it still didn't work in the sense that it gave me more errors. So I researched the new errors and found the new solution here: flutter/flutter#73852 (comment).

[lcuis]

Great if it worked at the end. Thanks for letting me know @samumzizi !
