Flutter Mobile App Splash Screen Animation — 3D Logo | Lottie Acceptable

We are looking for an experienced Flutter animation / mobile motion specialist to create a short, polished animated splash/loading screen for the Go Shop Black iOS and Android app. We already have: Finished approved 3D-style Go Shop Black artwork A screen recording of the existing animation Previous Lottie/JSON animation files for reference We do not need the logo redesigned. The goal is to recreate the existing concept using our new 3D branding. Animation Sequence The sequence is: GO → GO SHOP → full Go Shop Black logo → app opens The new animation must preserve the appearance of the approved artwork, including: Dimensional/glossy red shopping bag Green GO SHOP lettering with depth Metallic/dimensional BLACK lettering Raised-fist detail inside the A Shadows, highlights, depth, and reflections Correct letter shapes, including the openings inside the B The animation should feel clean, premium, smooth, and fast. Preferred Technical Approach Our preferred implementation is a native Flutter animation using optimized PNG/WebP artwork. For example, the supplied 3D artwork may be separated into: GO GO SHOP Full Go Shop Black logo and animated directly in Flutter using techniques such as: opacity/fade transitions scaling positioning cross-fades easing/timing We prefer this approach because preserving the exact 3D appearance of the supplied artwork is more important than converting everything into vector animation. Lottie Is Acceptable Lottie/JSON is also acceptable if you believe it is the better solution and you can: Preserve the 3D/dimensional appearance closely Keep the animation lightweight Avoid noticeably slowing app startup Deliver a mobile-ready animation that works well on both iOS and Android Lottie may use optimized raster/image assets if necessary. It does not need to be pure vector. Rive or another mobile-friendly method may also be proposed, but please explain why you recommend it. Important We are not looking for a video intro, MP4, or heavy GIF. This is a mobile app loading/splash experience and performance matters. Deliverables Depending on the agreed implementation: If Flutter-native: Optimized PNG/WebP animation assets Flutter animation implementation/code Implementation that works on both iOS and Android Source assets Screen recording showing the completed animation If Lottie: Optimized Lottie/JSON file Any required image assets Source After Effects/design file Preview animation Clear handoff instructions for our Flutter developer To Apply Please answer: Have you created Flutter splash/loading animations before? Have you worked with 3D-looking or dimensional logo artwork? For this project, would you recommend Flutter-native PNG/WebP animation or Lottie, and why? Approximately how many hours would you expect this to take? Please provide 1–3 relevant examples.
