ApsaraVideo Live:Demo compilation

For Dart 3.0 and above versions, the following error may occur when running pod install:

[!] CocoaPods could not find compatible versions for pod "Flutter":
In Podfile:
Flutter (from `Flutter`)
url_launcher_ios (from `.symlinks/plugins/url_launcher_ios/ios`) was resolved to 0.0.1, which depends on
Flutter
Specs satisfying the `Flutter (from `Flutter`), Flutter` dependency were found, but they required a higher minimum deployment target.

Solution: Open the Podfile in the example directory and modify the value of platform :ios, '' to 12.0.

If you encounter the error message "The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation", perform the following steps to resolve the issue:

1. Delete the Pods folder.

2. Delete Podfile.lock.

3. Execute pod install--repo-update.

4. Launch Xcode again and open your project.

If you encounter the error message "Type 'UIApplication' does not conform to protocol 'Launcher'", it may be due to a mismatch or missing implementation for the protocol Launcher.

Solution: Modify the code as follows.

/// Launcher is intentionally a direct passthrough to UIApplication.
extension UIApplication: Launcher {
    func open(_ url: URL, options: [OpenExternalURLOptionsKey : Any], completionHandler completion: ((Bool) -> Void)?) {
        self.open(url, options: options, completionHandler: completion)
        }
}
