I’ve found several articles comparing the accuracy of AI models for web development, but hardly any comparing the accuracy for Flutter development. I recently ran into an issue that only occurred when the debugger wasn’t attached, so I decided to put 3 of the top models to the test and share my results. In my experience: Claude 3.7 Sonnet Thinking is best suited for deep evaluation tasks. It’s more expensive and slower than 3.5 for code generation, but it excels at Flutter troubleshooting.
