I’m working on a Flutter project and set an environment variable for testing. However, during integration tests, the variable is not accessible. Here’s what I did:

Set an environment variable:

export my_key='your_api_key_here'

Verified the environment variable:

echo $my_key

Tried accessing it in the Flutter test with and both of them are not working

const key = String.fromEnvironment("my_key")
final key1 = Platform.environment['my_key']

Checked all environment variables and saw that my_key is not there. The environment is different.

Ran the tests with:

flutter test integration_test/test_feature.dart -d emulator-5554

The environment variable my_key is not accessible during the test. It seems the test environment is isolated and does not inherit my terminal’s environment variables.

How can I ensure my Flutter integration tests access the environment variables I set? Any recommendations to pass environment variables to the Flutter test environment?
