To make sure your .gradle files are in the appropriate format, you can refer to:

• Add documentation for migrating Android build files to declarative form flutter/flutter#135392
• Your project requires a newer version of the Kotlin Gradle plugin flutter/flutter#137886 (comment)
• This project's example app

having the same issue in location: ^6.0.1
I have added the below code to my build.gradle file

buildscript {
ext.kotlin_version = '1.9.23'
repositories {
    google()
    mavenCentral()
}

   dependencies {
       classpath 'com.android.tools.build:gradle:8.3.1'
       classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
   }
}

and update the distribution URL to this
distributionUrl=https\://services.gradle.org/distributions/gradle-8.7-all.zip

still getting the same error to update the kotlin version

[hitarthparmar0412]

`buildscript {
ext.kotlin_version = '1.9.23'
repositories {
google()
mavenCentral()
}

dependencies {
    classpath 'com.android.tools.build:gradle:8.1.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

}

}`

I got an error

The following dependencies do not satisfy the required version:
project ': location' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.20
