What are the pros and cons of building a cross-platform app using Flutter?

Flutter has gained popularity for developing cross-platform applications, allowing developers to write code once and deploy it on both iOS and Android. However, there are both advantages and disadvantages to consider. Pros include faster development times, a single codebase, and a rich set of pre-designed widgets. On the other hand, potential cons might involve performance issues compared to native apps, limited access to platform-specific features, and larger app sizes. What has been your experience with Flutter in full stack development? Have you faced any challenges or found any best practices?
