test/variable_test.dart:66

• [nitpick] Duplicate test description for 'builds variable object from a map with eval reason'. Give each test a unique name to improve readability and debugging.

  test('builds variable object from a map with eval reason', () {

lib/dvc_variable.dart:49

• The fromDefault path sets a default eval reason but isn’t covered by tests. Add a unit test to verify that defaultReason is applied correctly.

        eval: DevCycleEvalReason.defaultReason("User Not Targeted"));

lib/dvc_variable.dart:48

• mapType is undefined in fromDefault, causing a compile error. Consider deriving the variable type from defaultValue or adding a parameter for the type.

            .firstWhereOrNull((e) => e.toString() == "VariableType.$mapType"),
