• Performance Overhead
  Incorporating many complex widgets and features can lead to performance issues, especially in applications that require real-time data processing or operate in resource-constrained environments.
• Dependency on Vendor
  Relying on a third-party UI library can create dependency on the vendor for updates and new features, which may not always align perfectly with a project’s timelines or specific needs.
