Flutter is famous for its 60fps performance, but achieving that on low-end Android devices requires deep optimization.
1. Impeller Rendering Engine
Impeller is the new default rendering engine that eliminates shader compilation jank. Ensure it is enabled in your AndroidManifest to guarantee smooth animations from the very first frame.
2. Use `const` Everywhere
Marking widgets as `const` tells Flutter they don't need to be rebuilt when `setState` is called. This is the single biggest performance win for large lists.
3. Tree Shaking & Obfuscation
Use the `--obfuscate` flag when building your APK. This not only secures your code but removes unused library code, significantly reducing app size for users with slow internet.
