Description

Experience Level: Expert
Estimated project duration: 1 - 6 months
One of our clients is looking for an experienced Flutter developer or agency to design, develop, and deliver a cross-platform mobile application using Flutter (frontend) and PHP/Laravel (backend API). The project spans 6 months and requires a disciplined, milestone-driven approach.

We are open to working with a team of skilled developers or agencies. What matters most is your attention to detail, your technical approach, and the quality of your previous work. Specs are attached and create your proposal according to that.

Tech Stack Required
Flutter (Dart) - cross-platform iOS & Android
PHP / Laravel - RESTful API backend
MySQL or PostgreSQL - relational database
Firebase or similar - for push notifications, optional real-time features
CI/CD pipeline setup (GitHub Actions, Bitbucket, or equivalent)
App Store & Play Store deployment experience
What I Need in Your Proposal
Please do not send a generic response. We will only consider detailed proposals that include all of the following:

A proposed system/app architecture diagram or description (frontend, backend, database, third-party integrations)
A clear delivery plan broken into milestones with timelines and deliverables per phase
Cost breakdown per milestone (or overall fixed-price structure)
Links or descriptions of 2-3 similar or relevant projects you have built (portfolio/previous work)
Any assumptions, questions, or suggestions you have based on the project brief

Selection Criteria
Attention to detail in your proposal - generic bids will not be reviewed
Quality and relevance of previous work / portfolio
Demonstrated experience with Flutter + Laravel stack specifically
Realistic milestone planning and cost transparency

Next Steps
Shortlisted candidates will be invited for a call to discuss their proposal in detail, align on project scope, and agree on final terms. Please include your availability for a call in your proposal. Kindly begin your proposal with the word “Champion” to confirm that you have thoroughly reviewed the project details.

NOTE - currently mentioned cost is a placeholder. We would like to have a realistic cost for the project.

Looking forward to having the best team on board.

Clarification Board Ask a Question

  • Asad C.

    - For the offline-first functionality, how critical is real-time conflict resolution when the same data is modified across devices, and do you have any specific rules in mind for handling sync conflicts?

    - Regarding the document annotation feature (crop, draw, text), do you expect basic functionality or a more advanced tool similar to professional markup tools, and should edited files maintain version history?

    - For subscriptions and payments, do you already have merchant accounts and pricing logic finalized, including recurring billing, promo codes, and regional payment handling, or should this be designed from scratch?

    - On the company user side, how do you envision scaling the gift certificate system, should it support large bulk operations (thousands of emails), tracking, and reporting, or remain relatively lightweight?
