Flutter app development

Hire Dedicated Flutter Developers for Cross-Platform Mobile Applications.

Q: Why should we choose Flutter instead of separate native iOS and Android apps?

Flutter is often a good fit when you want a single codebase, consistent UX and faster iteration across iOS and Android. It can reduce time to market and ongoing maintenance costs while still delivering native-feeling performance. If there are cases where native is a better fit, we will say so during discovery.

Q: Can you integrate Flutter apps with our existing backend and authentication?

Yes. We regularly integrate Flutter clients with existing APIs, authentication systems, payment gateways, analytics tools and third-party SDKs. If your backend needs changes to support mobile use cases or offline behaviour, our web/backend teams can help shape that work as well.

Q: How do you handle QA and app store submissions for Flutter projects?

We treat QA and release management as part of the engagement, not an afterthought. That usually includes device testing on key form factors, basic automation for critical flows, crash monitoring setup and support for preparing store listings, builds and submissions to the Apple App Store and Google Play Store.

Q: Who owns the Flutter app code and store accounts?

You own the Flutter source code, assets and IP after payment, and store accounts remain under your control. We can help set up accounts and CI pipelines, but everything is configured so that you are not dependent on us to keep the app running in the long term.

Q: How long does it usually take to launch a first Flutter app version?

Timelines depend heavily on scope, design readiness and backend complexity. A lean but meaningful v1 often takes between eight and sixteen weeks from discovery to store release. During discovery we map out a realistic MVP for the app and then provide a timeline based on that agreed scope.

QalbIT provides Flutter developers who specialise in designing and building cross-platform mobile apps with a single codebase. We focus on solid architecture, smooth user experiences, offline-ready behaviour and release processes that you can trust for the long term.

Flutter hiring snapshot

Typical engagement: Dedicated Flutter squad or fixed-scope mobile app project
Core focus: Product-grade mobile apps for iOS and Android
Time to start: 2–4 weeks after scope, priorities and app stores strategy are aligned
Delivery model: Discovery and pilot release first, then ongoing feature sprints

We typically start with a short discovery to understand your goals, constraints, existing stack and timelines – then propose a practical roadmap across architecture, UX and delivery.

Flutter overview

When hiring Flutter developers with QalbIT makes sense

We work with teams that treat mobile as a first-class channel – whether for customers, partners or internal staff – and need a reliable Flutter squad to deliver and maintain those apps.

When a dedicated Flutter team is the right move

You want to launch or evolve a cross-platform mobile app without maintaining separate native codebases.
You need to complement an existing web or SaaS platform with mobile apps for key flows and notifications.
Your current Flutter app is unstable, under-documented or hard to extend, and you need a senior squad to stabilise it.
You prefer a mobile partner who considers UX, device constraints and real-world usage patterns instead of just screens.
You need predictable Flutter capacity for roadmap work, not just one-off releases.

Outcomes we target for Flutter engagements

Smooth, responsive mobile experiences that feel native on both iOS and Android.
Stable releases with proper QA, crash monitoring and app store compliance.
Architecture that supports modular features, offline modes and background tasks.
Predictable release cycles aligned to marketing or product milestones.
Documentation and knowledge transfer so you are not tied to a single vendor.

Most Flutter engagements start with a short discovery and design review. This helps us clarify scope, prioritise the first release and ensure the architecture can grow with your product.

How it works

A practical process for hiring and working with Flutter developers

We keep mobile delivery structured: clear milestones, visible builds and realistic expectations around app store approvals.

01

Discovery & app definition

1–3 weeks

Understand your users, use cases, required platforms, integrations and constraints. Clarify what must be in v1 vs later releases.

Key outcome: Documented app scope, user journeys and technical assumptions.
02

UX, UI & architecture

2–4 weeks

Create or refine flows, screens and Flutter architecture, aligning with your brand and backend capabilities.

Key outcome: Agreed designs and technical plan for a realistic first release.
03

Incremental Flutter development

4–12+ weeks (scope-dependent)

Build app features in reviewable increments, with test builds shared to stakeholders regularly.

Key outcome: A working Flutter app ready for pilot users or internal testing.
04

Pilot, launch & app stores

2–4 weeks

Support pilots, refine UX, prepare app store listings and guide submissions through approval.

Key outcome: Apps live on app stores, with monitoring and feedback loops in place.
05

Ongoing improvements & support

Ongoing, month-to-month

Ship new features, handle OS updates, track crashes and continually improve performance and UX.

Key outcome: Mobile apps that stay healthy and aligned with your product strategy.
