Code Review

This pull request updates the package_info_plus_tizen plugin to version 1.1.0, adds support for PackageInfo.installTime, and updates the minimum Flutter and Dart versions. It also includes updates to the example application and integration tests. A critical issue was identified in the C++ implementation where the installed_time variable should be declared as time_t instead of int to ensure type compatibility with the Tizen API and prevent potential memory corruption or overflow issues.
