/// FORCE_UPDATER INTERACTIVE PLAYGROUND & EXAMPLE
/// ---------------------------------------------------------------------------
///
/// This example showcases how to implement and test the `force_updater` package.
/// It provides a dynamic interactive interface letting you test all 5 premium
/// visual styles, switch between inline simulator configs, and inspect how
/// the updater behaves in real-time.
///
/// To test the package:
/// 1. Run the local mock API server: `dart example_api.dart`
/// 2. Launch this app on your Emulator or Web browser.
/// 3. Toggle styles and configuration settings below to see immediate updates!
/// ---------------------------------------------------------------------------
// Global Notifiers to make the example highly interactive in real-time!

//
// if (Semver.isLessThan('1.0.0', info.minVersion)) {
// showMyFullyCustomBlockingWall(context);
// } else if (Semver.isLessThan('1.0.0', info.latestVersion)) {
