[fooshyangsong]

Hello everyone, I am currently working on A/B testing for my app. I required to get instance id token in order to validate my experiment on a test device. I had look through the helpline but it doesn't provide a sample for flutter. https://firebase.google.com/docs/ab-testing/abtest-config?authuser=0#validate_your_experiment_on_a_test_device
