Flutter app development

Flutter apps that do real work on the device.

Every Flutter app we have shipped does more than draw screens over an API: notification parsing, local encryption, background services. Where a feature needs the platform itself, we drop to Kotlin or Swift through a platform channel instead of waiting for a package to appear.

01

Flutter apps

One Dart codebase for Android and iOS with Firebase or Supabase behind it. We reach for Flutter when the product is the same on both platforms and a real store release matters more than platform specific chrome.

What we build

  • Consumer apps with offline first data
  • Internal tools for field and sales teams
  • Subscription and payment flows
  • Store submission, phased rollout and the review responses that go with it

What you get at handover

A repo in your organisation, signed releases on both stores, CI that builds from your main branch, and crash and analytics dashboards handed over in your accounts.

Engagement shape

Discovery sprint, then a build in two week increments with a working demo at the end of each.

  • Hive
  • Play Console
  • App Store Connect
Our drivers work in basements and cold rooms where the network drops for hours, so the app had to keep functioning without it. Kyron built the Flutter app around a local queue with proper conflict rules instead of blind retries, and we have not lost a delivery record since go live. Crash free sessions sit at 99.4 percent across 430 devices. The handover documentation was better than what our previous vendor left behind.

However we work together

  • You own the IP. It transfers on final payment and it is written into the statement of work, not only the master agreement.
  • We sign your NDA, or ours, before the first technical call.
  • Repos, cloud projects and store accounts are created in your name on day one, and our access is revoked at project close.
Flutter apps, in practice

What clients ask about this one.

On the parts that matter, yes: scroll physics, navigation, keyboard behaviour and store compliance. Where it will not is when the platform APIs are the product, and on that we recommend native instead, even when it costs us the bigger project.

Yes, both stores, including the data safety and privacy declarations, phased rollout, and the responses when a review is rejected. The accounts stay in your name throughout.

It is part of the support agreement: a monthly dependency and OS compatibility pass, with a written report of what changed and what it needs.
