incorrect-firebase-parameter-name

added in: 1.21.0

warning

Pro+

Warns when the parameter name does not comply with Firebase limitations.

Firebase requires the parameter name to contain 1 to 40 alphanumeric characters or underscores and start with an alphabetic character.

Example

❌ Bad:

void fn() {
  _analytics.logEvent(name: '', parameters: {
    // LINT: Incorrect parameter name. Parameter names should contain 1 to 40 alphanumeric characters or underscores and start with an alphabetic character.
    'some-name': 'str',

    // LINT: Incorrect parameter name. Parameter names should contain 1 to 40 alphanumeric characters or underscores and start with an alphabetic character.
    '': 'str',
  });
}

✅ Good:

void fn() {
  _analytics.logEvent(name: '', parameters: {
    'some_name': 'str',
  });

  _analytics.logSignUp(signUpMethod: '', parameters: {
    'correct_param': 'str',
  });
}
