Deliver a shared mobile codebase with a clear platform plan.
Use Flutter where a shared codebase fits the product. Review platform-specific requirements early so essential native integrations are included in the architecture and test plan.

Overview
Flutter Development, explained
Flutter lets one team build apps for iOS, Android and the web from a single codebase while keeping smooth, consistent interfaces. It is a strong choice for products that need to launch on several platforms without doubling effort.
We have used Flutter in production, including a mobile image processing app for scientists in the US and a note-taking app that uses machine learning to parse natural language. We build Flutter apps with clean architecture, native integrations where needed and automated release pipelines.

Why PoliteTech
Why teams choose PoliteTech
Scope before commitment
Priorities, assumptions and acceptance criteria are agreed in writing before a delivery plan is fixed.
Engineers who build
Recommendations come from the people who design, code and support the software, so they reflect real implementation effort.
Visible progress
A shared backlog, regular demos and recorded decisions keep you informed without chasing updates.
Practical AI
Evaluation sets, review steps, cost limits and monitoring are part of every AI feature we ship.
Flexible engagement
Start with a scoped project, a dedicated team or support, and change the model as your roadmap evolves.
Clear ownership
Repositories and accounts can live in your organisation, with IP and confidentiality terms agreed in the contract.
Industries
Where this work fits
Retail and Ecommerce
Build web and mobile journeys around product discovery, ordering and customer service.
Financial Software
Support reporting, document processing and internal operations through defined application workflows.
Logistics Software
Connect planning, task assignment and operational updates in one workflow.
Education and Elearning
Create platforms for content, activities and progress tracking.
Fitness and Wellness Apps
Support tracking, coaching content and user engagement around a clear product goal.
Manufacturing Software
Replace fragmented tracking with workflows for quotations, work status and supporting documents.
Real Estate Applications
Create listing, enquiry and internal coordination tools around your business process.
Business Operations
Build task, approval and reporting tools around the way your team works.
Process
A practical path from requirements to release.
Each stage ends with something you can review: a scope, a prototype, a working increment or a release.
01
Understand
Discuss your users, business needs, existing systems and delivery constraints.
02
Define
Agree scope, technical approach, responsibilities and a delivery plan.
03
Design and build
Develop in manageable increments with visible progress and review points.
04
Test and release
Validate agreed workflows, resolve release blockers and prepare deployment.
05
Support and improve
Document the handover, review production feedback and plan the next priorities.

Cost
What shapes the cost of your project?
There is no useful price without scope. These are the factors we review when preparing an estimate, and the estimate lists every assumption so you can see what would change it.
01
Platforms
Web, iOS, Android or all three, and whether apps are native or cross-platform.
02
Features and roles
The number of user journeys, roles and business rules in the first release.
03
Integrations
Payments, maps, CRMs, ERPs and third-party APIs each add scope.
04
Design depth
From using a component library to a fully custom design system.
05
Data migration
Moving and validating data from existing systems.
06
Non-functional needs
Performance, security, availability and compliance requirements.
Engagement models
Choose the engagement that fits your next step.
Dedicated Team
For a changing roadmap or ongoing development. Agree roles and working process, then manage priorities through a shared backlog.
Best for team extension and long-term product work.
Scoped Project
For a defined product or milestone. Align on requirements, deliverables and acceptance criteria, with changes reviewed before they affect the plan.
Best for MVPs, integrations and focused releases.
Maintenance and Improvement
For software that already exists. Start with a technical review, then agree support routines and planned improvements.
Best for live applications and modernisation.
FAQ
Questions about Flutter development
Is Flutter good for production apps?
Yes. It is used widely in production and performs well for most business apps.
Flutter or React Native?
Both are good. Flutter offers consistent UI and strong performance; React Native suits teams with JavaScript skills. We recommend based on your context.
Can Flutter access device features?
Yes, through plugins and native code where needed.
Can we use Flutter for the web too?
Yes, for many app-like experiences; content-heavy websites are better built with web technologies.
Can you take over our Flutter app?
Yes, after a code review.
How do you test Flutter apps?
Widget, integration and device tests in CI.
Can we begin with a focused scope?
Yes. We can review your current situation and agree a bounded first engagement before a wider build.
How are pricing and timelines determined?
We review requirements, technical complexity, team needs and delivery constraints before proposing an engagement. Estimates list assumptions and what may change the plan.
Can we discuss a project under an NDA?
Yes. Let us know before sharing confidential materials so we can agree confidentiality terms first.
