This change should not require a version bump since it is a documentation change mostly

Code Review

This pull request adds a dartdoc example for the OpenContainer widget and updates the CHANGELOG.md to reflect this change. The example demonstrates how to use OpenContainer with openBuilder and closedBuilder. My review provides a suggestion to simplify the example code for clarity and adherence to Dart style conventions.

[gemini-code-assist]

For a clearer and more idiomatic example, I have a few suggestions:

• In closedBuilder, the GestureDetector is redundant because OpenContainer is tappable by default. It's simpler to rely on the default behavior. The action callback is useful for more complex scenarios, like when tappable is set to false.
• The action parameters in both openBuilder and closedBuilder are unused in this example. It's a good practice to rename them to _ to signify they are intentionally ignored.
• Per the Dart style guide, it's preferred to use single quotes for strings.

I've applied these changes in the suggestion.

/// OpenContainer(
///   transitionDuration: const Duration(milliseconds: 500),
///   transitionType: ContainerTransitionType.fadeThrough,
///   openBuilder: (context, _) {
///     return Scaffold(
///       appBar: AppBar(title: const Text('Details Page')),
///       body: const Center(
///         child: Text(
///           'This page opened with Container Transform animation',
///           style: TextStyle(fontSize: 18),
///           textAlign: TextAlign.center,
///         ),
///       ),
///     );
///   },
///   closedBuilder: (context, _) {
///     return Container(
///       width: 200,
///       height: 120,
///       alignment: Alignment.center,
///       decoration: BoxDecoration(
///         color: Colors.blue,
///         borderRadius: BorderRadius.circular(16),
///       ),
///       child: const Text(
///         'Open Details',
///         style: TextStyle(color: Colors.white, fontSize: 18),
///       ),
///     );
///   },
/// ),

Hey @AbdeMohlbi thanks for the PR! Actually, examples do typically require a version bump and release since this is changing the public documentation.

Hi @ @AbdeMohlbi ! Can you bump the version in CHANGELOG.md and pubspec.yaml ?

I plan on doing that soon, i will mark as draft for the moment, thanks and sorry for the delay.

Code Review

This pull request adds a usage example to the OpenContainer widget's documentation, resolving a TODO item. It also increments the package version in pubspec.yaml and adds a corresponding entry to CHANGELOG.md. My review identified a syntax error in the newly added example code which would prevent it from being runnable. I have provided a suggestion to correct this.

The example looks good to me except a nit
