What are your best practices or tips for reducing the overall app size in Flutter projects? Do you focus more on image optimization, removing unused dependencies, code splitting, or something else?

🚀 Great question! Reducing Flutter app size is something I’ve been experimenting with too, and I’ve found that it’s never just one trick — it’s usually a mix of small optimizations that add up:

Images first! I always compress PNG/JPGs into WebP or use SVGs whenever possible. Tools like TinyPNG are lifesavers.

Dependencies check. I try not to add a heavy package for a tiny feature. A few lines of custom code are often lighter than pulling in a full library.

Build tricks. Using flutter build appbundle --release keeps Play Store delivery optimized, and --tree-shake-icons removes unused icons (super underrated tip).

Fonts & assets. Keeping fonts limited and avoiding extra weights/styles makes a noticeable difference.

Split per ABI. For testing APKs, I usually run --split-per-abi so users don’t download unnecessary binaries.

So for me, it’s a balance: image optimization + dependency hygiene + build flags = smaller, faster apps ✅

I’d also love to hear if anyone here has tried lazy loading certain modules in Flutter for size reduction — curious if it’s effective in real-world projects. 👀

Insightful, thanks for sharing this!

Optimize Assets

Why: Images, fonts, and other resources often make up the largest portion of an app.
Tips:

Use proper formats:

PNG for simple graphics, WebP for photos (smaller and supports transparency).

SVG for vector graphics instead of PNG where possible.

Resize and compress images: Don’t include high-resolution images if not needed. Use tools like TinyPNG
or ImageOptim
.

Lazy-load assets: Only load assets when needed instead of bundling everything at startup.

Remove unused assets: Keep your assets/ folder clean
