Exactly same issue here also, tried with below solution but did not worked as well

make below change in app/build.gradle
constraints {
implementation('com.facebook.android:audience-network-sdk') {
version {
strictly '6.8.0'
}
}
}

from facebook_audience_network.

is there any other way to show facebook ads in flutter app ?

from facebook_audience_network.

One solution worked for me

I have changed the version from 6 to 5 and it's worked for me.

try below dependency

implementation 'com.facebook.android:audience-network-sdk:5.+'

from facebook_audience_network.

@KuldeepVagadiya not working

from facebook_audience_network.

@KuldeepVagadiya your solution not supported null safety and also not working

here someone give me this solution on stack-overflow please check maybe its help for us. In pubspec.yaml depend on https://github.com/azmasamy/facebook_audience_network.git instead of facebook_audience_network: ^1.0.1

facebook_audience_network: ^1.0.1

facebook_audience_network:
git:
url: https://github.com/azmasamy/facebook_audience_network.git
ref: master

from facebook_audience_network.
