In profile mode, some debugging ability is maintained—enough to profile your app’s performance.
Profile mode is used when you want to analyze performance.
Profile mode is disabled on the emulator and simulator, because their behavior is not representative of real performance.
On mobile, profile mode is similar to release mode, with the following differences: – Some service extensions, such as the one that enables the performance overlay, are enabled. – Tracing is enabled, and tools supporting source-level debugging (such as DevTools) can connect to the process.
Profile mode for a web app means that: – The build is not minified but tree shaking has been performed. – The app is compiled with the dart2js compiler.
The command flutter run --profile compiles to profile mode.
