PWA Functionality: While Flutter web can be used to build Progressive Web Apps (PWAs), achieving full PWA functionality, such as offline support and background sync, might require additional configuration and work.
Learning Curve for Web Developers: Developers coming from a web background might need time to adjust to Flutter's reactive UI model and widget-based approach, which can have a steeper learning curve.
Limited Third-Party Integrations: Some third-party integrations that are readily available in traditional web development might not have equivalent solutions in the Flutter ecosystem, leading to more manual integration work.
