The author conducted a performance analysis of Flutter web applications compiled to WebAssembly compared to traditional JavaScript. The study aimed to verify the actual speed improvements in rendering interfaces for large-scale projects.
Initial expectations for performance gains reached up to 50 percent, but practical tests showed a more modest increase of 5 to 10 percent. The research focused on identifying which specific operations benefit from the transition and how computation impacts overall interface fluidity.
To investigate the discrepancy between official performance claims and real-world results, a dedicated Flutter test environment was established. The analysis examines the interaction between WASM and JavaScript execution to understand the limitations of current compilation methods.
