@mjaydeep01 sorry that you are facing this issue and thanks for reporting it. would you share the the Gradle distributionUrl from the android/gradle/wrapper/gradle-wrapper.properties please.

[mjaydeep01]

@NikaHsn, its, distributionUrl=https://services.gradle.org/distributions/gradle-7.6.3-all.zip

[NikaHsn]

@mjaydeep01 The issue you're encountering appears to be related to version incompatibilities in your Android build setup.
With Ampliy Flutter 1.8.0 android dependecies are updated, would it be possible for you to update your project to use below versions?

• amplify flutter 1.8.0
• kotlin version 1.9.10
• java version 17
• gradle version 8.1.0
• gradle distribution url 8.1 (distributionUrl=https://services.gradle.org/distributions/gradle-8.1-all.zip)
