Poem

🐰 In the realm of widget tests so bright,
Visibility dances left and right,
PostContainer's secrets now unfurled,
With keys unique and states uncurled,
A testing rabbit's pure delight! 🧪

15-16: Consider using a placeholder URL or local asset for photoUrl.

Using an external image URL in tests might cause issues if the URL becomes inaccessible or changes. Consider using a placeholder URL or a local asset to improve test reliability.


Line range hint 95-109: Simplify the disposal test using expect with throwsAssertionError.

You can use expect with throwsAssertionError to make the test cleaner instead of using a try-catch block.

Apply the following diff to simplify the test:

 await tester.pumpWidget(
   MaterialApp(home: Container()),
 );

-try {
-  pageController.position;
-  fail('Should throw AssertionError');
-} catch (e) {
-  expect(e, isInstanceOf<AssertionError>());
-}
+expect(() => pageController.position, throwsAssertionError);

124-309: Consider refactoring tests to reduce code duplication.

Multiple test cases have similar setup and patterns. Extracting common code into helper functions or using parameterized tests will enhance maintainability and readability.
