# Experts in Flutter development for cross-platform apps

https://www.mecexis.com/en/technologies/flutter/

Development of cross-platform apps with Flutter for iOS and Android, with an interface adapted to your product.

We have been developing applications with Flutter since 2018. We help you define, design and connect your app with the services and data it needs.

## Flutter for cross-platform apps

A shared base, a carefully designed experience

Flutter allows you to develop applications for different platforms with Dart. Sharing a significant part of the code helps coordinate the development and evolution of the app.

Every device is unique. We consider integrations, offline usage, and key journeys before deciding what is shared and what needs adaptation.

## What does it bring to your app?

Sharing code makes sense when it makes it easier to build and maintain the product.

### Shared development

A common foundation for iOS and Android reduces duplicate work. The specific savings depend on the functionalities and adaptations of each platform.

### Consistent design

We can maintain a common visual identity and adapt navigation and interactions to the expectations of each device.

### Custom interfaces

The components allow you to build your own screens and interactions, with attention to accessibility and different screen formats.

### Coordinated evolution

Shared improvements are developed on the same foundation. Publishing and testing are managed for each platform.

### Performance testing

We test important journeys on real devices. Animations, data, and connections are adjusted based on the results.

### Product maintenance

A clear structure and well-chosen dependencies make it easy to incorporate functionalities and adapt to system updates.

## What applications can we build?

We start from the use that the product should have, not from a list of functionalities.

- Apps for fans and sports organizations
- Mobile portals for customers
- Work tools for teams
- E-commerce and catalog browsing
- Content browsing and playback
- Data collection and forms
- Apps connected to services and devices

## How we prepare the technical base

Decisions oriented towards the actual use and maintenance of the application.

### Presentation and performance

We review how screens are drawn and updated. We measure demanding user journeys before considering performance as resolved.

### Adaptation to each screen

We define how the interface behaves on different sizes and platforms, including enlarged text, keyboard, and touch zones.

### Reusable widgets

We organize screens with widgets, Flutter's interface components. Sharing them maintains consistency and avoids unnecessary duplication.

### State management

We separate data, operations and presentation. We choose a structure that is proportionate to the product and easy to follow.

### Behavioral tests

We check logic and critical paths, including connection errors and unexpected responses from services.

### Device integration

We assess the available plugins and the native adaptations necessary to access features such as the camera or notifications.

## Your mobile project, from start to finish

We define what the product needs and how we will build it with your team.

Developing with Flutter since 2018.

### Experience since 2018

We have been working with Flutter since its beta stage. This experience helps us prepare the architecture, integrations, and maintenance of each application.

### Clear scope and budget

We assess what can be shared between platforms and which parts need specific work. The budget depends on the functionalities, integrations and testing required, without universal savings percentages.

### Quality checks

We define tests based on the important app flows and expected devices. We review behavior against errors, unstable connections, and incomplete data before launch.

### Planned publication

We prepare the versions and publishing requirements for each store. We agree on the schedule taking into account the review processes and differences between platforms.

### Product evolution

After launch, we can support maintenance and new features. We prioritize changes with your team based on usage and business needs.

> Flutter allows us to create native apps for iOS and Android with a single codebase, maintaining exceptional quality and performance on both platforms.
