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
- 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-infoand--obfuscateto strip symbols.
