Release 0.5.0

[LukGaming]

Add this to the end of the File basic_assertions, then we have VerifyAllAssertions for lists
and we can have
ShouldAllSatisfyExtension of lists

extension VerifyAllAssertions<T> on T? {
  // Asserts that a Each item of the list is an instance of [E].
  /// [E] - Expected type.
  void shouldAllBeInstanceOf<E>() {
    (this as List).forEach((element) {
      expect(element, isA<E>());
    });
  }
}

// Usage
 test(
    "Verify That getServices() return a List of Services",
    () => {servicesList.shouldAllBeInstanceOf<Service>()},
  );

//Given an List, check multiples assertions in a list
extension ShouldAllSatisfyExtension<T> on List<T> {
  void shouldAllSatisfy(void Function(T) assertion) {
    for (final item in this) {
      assertion(item);
    }
  }
}

// Usage
  test(
    "Verify That All Service Fields Are not Null",
    () => {
      servicesList.shouldAllSatisfy((service) {
        service.serviceDone.shouldNotBeNull();
        service.serviceName.shouldNotBeNull();
        service.serviceDoneDay.shouldNotBeNull();
      })
    },
  );

Thank you for your input @LukGaming. The 0.5.0 release is going to contain methods that meet your needs:

test(
    "Verify That getServices() return a List of Services",
    () {
        servicesList.shouldAllBeInstanceOf<Service>();
    },
);

test(
    "Verify That All Service Fields Are not Null",
    () => {
      servicesList.shouldContainAllThat((service) {
        return service.serviceDone != null &&
               service.serviceName != null &&
               service.serviceDoneDay != null;
      });
    },
);
