IGTCODE Services Serbia
Flutter mobile app development
IGTCODE is a software development company in Serbia using Flutter for business, organisation and startup apps locally and internationally. We connect Flutter development with backends, APIs and administration, from the first version to Android and iOS publishing.
What is Flutter?
Flutter is a framework for building applications from a shared codebase using Dart. Cross-platform development shares much of the interface and logic between Android and iOS. Platform-dependent integrations still need dedicated attention and testing.
Which projects do we use it for?
We use Flutter for apps with accounts, membership, events, offers and maps. The IGTCODE portfolio lists Flutter for Mensa Serbia, the Serbian School Sports Federation and Transporter. Technology choices are confirmed against each project's requirements.
iOS and Android from one codebase
Shared code helps develop and align features. Not every task is shared: sign-in, push permissions, payments, deep links and device behaviour must be checked on both platforms. Testing covers different screen sizes and real devices.
Backends, APIs and connected services
We connect Flutter interfaces with REST APIs and backend business logic. Firebase services such as Cloud Messaging, or Supabase, can form part of the architecture where appropriate. Databases, authorisation and privileged operations have a clearly defined server boundary.
Performance and deployment
We monitor asset sizes, screen responsiveness and slow network requests. We optimise where measurements show a need, and prepare production builds, platform testing and store submissions.
Flutter development for international teams
IGTCODE works with businesses, organisations and startups in Serbia and abroad. We agree scope, communication, delivery stages and responsibilities so mobile development can fit the client's existing team and systems.
Technologies and tools
We choose technology around the requirements and existing system. The specific stack and each service's role are agreed during planning.
How does development work?
Scope and platform needs
Clarify users, core workflows and device-specific requirements.
Architecture and interface
Define shared code, APIs and user journeys.
Development and device testing
Build in stages and check Android and iOS separately.
Publishing and support
Prepare store releases and agree the next development steps.
Questions before we start.
Is Flutter suitable for both iOS and Android?
Yes. Much of the app can share code, with platform-specific configuration and testing for both systems.
Does one codebase mean there is no separate platform work?
No. Permissions, payments, notifications, deep links and device behaviour still need checks and configuration on each platform.
Can Flutter connect to an existing backend?
Yes, where suitable APIs and access are available. We first review authentication, data structures and business rules.
Do you use Firebase or Supabase with Flutter?
They can be part of the architecture where they fit the requirements. The choice depends on the project, access rules and maintenance needs.
How do you check performance?
We measure responsiveness and behaviour on real devices, especially with long lists, images and slow networks. Optimisation addresses specific observed problems.
Do you work with clients outside Serbia?
Yes. We work with international teams and agree communication, delivery milestones, access and responsibilities in advance.
