Server-Side Rendering for Flutter Web: Promising Paths or Dead End
summary
Tests show a ~7 MB Flutter Web bundle that delays first meaningful paint leading to ~8 second waits in some setups so 30% of users drop off and a 2.5 month effort explores fixes and SSR options. Running the deprecated HTML renderer with a headless browser yields visually correct but absolutely positioned output with no semantic structure. The semantic tree exposes text and improves indexing but lacks visuals. A screenshot fallback boosts perceived FCP but breaks responsiveness and interactivity. Practical wins come from URL strategy, tree shaking, modern image formats, compression, cache headers and dynamic HTML or schema for crawlers.
