How do you reduce the app size (APK/IPA)?

Updated Apr 28, 2026

Short answer

By using app bundles, tree shaking, asset optimization, and obfuscation.

Deep explanation

  1. Build AAB (Android App Bundle) instead of APK to let Google Play serve optimized APKs per device. 2. Dart automatically tree-shakes unused code. 3. Compress images and use SVGs. 4. Remove unused fonts and packages. 5. Use --split-debug-info and --obfuscate to strip symbols.
