flutter-app-size

Measure and optimize Flutter app bundle, APK, or IPA size with platform-specific analysis and reduction strategies. Analyzes and optimizes Flutter application size by measuring build artifacts, generating size analysis reports, utilizing Dart DevTools for component breakdown, and implementing specific size reduction strategies such as debug info splitting, resource compression, and platform-specific tree-shaking. Assumes a configured Flutter environment and target platform availability. Use the following decision tree to determine the correct measurement and optimization path: Determine Target Platform and Baseline STOP AND ASK THE USER: "Which platform (apk, appbundle, ios, linux, macos, windows) are you targeting for size optimization, and do you have a specific size reduction goal?" Generate Size Analysis File Execute the Flutter build command with the --analyze-size flag to compile Dart with code size usage recording. Note: This generates a *-code-size-analysis_*.json file in the build/ directory and prints a high-level summary to the terminal. Generate iOS App Size Report (iOS Only) If targeting iOS, the .app file generated by --analyze-size only evaluates relative size. For an accurate end-user download estimate, generate an Xcode App Size Report. Analyze Components in DevTools Launch DevTools to inspect the JSON analysis file.
