How can i solve this issue

Thanks in advance. Your efforts will be appreciated.

Solution is here

FlexboxLayout 1.1.0, the library is expected to use with AndroidX.

If you want to use 1.1.0 and above than migrate to AndroidX

For AndroidX use this

dependencies {
    implementation 'com.google.android:flexbox:1.1.0'
}

For com.android.support:appcompat

dependencies {
    implementation 'com.google.android:flexbox:1.0.0'
}

For more information please check FlexboxLayout Hope this help others
