Pros of Using Flutter Web

  1. Code Reusability: Use a single codebase for iOS, Android, and web apps, reducing development time and cost.
  2. Unified Development Environment: No need to switch between different languages or environments. Also includes a hot-reload feature for faster code compilation and changes.
  3. Expressive UI and Customizable Widgets: Offers a plethora of customizable widgets and UI features. Excellent support for animations aids in building engaging applications.
  4. Performance: As a compiled language, Flutter matches the performance of native apps.

Cons of Using Flutter Web

  1. Larger App Size: Flutter Web apps are typically bulkier than their counterparts, potentially causing slower load times.
  2. Less Common Language (Dart): Dart, though powerful, isn't as popular as JavaScript or TypeScript, making it harder to find experienced developers.
  3. Limited SEO Support: Projects emphasizing SEO might need to combine Flutter Web with other frameworks, like Angular. This can introduce extra maintenance, but for non-SEO focused projects, Flutter Web remains a good option.
