Flutter Migration in Bristol
Migrating Bristol applications to Flutter, where the incremental route is possible and the seam is real. Flutter screens can be embedded into an existing native app, and every boundary between the two worlds costs something — navigation state, shared data and memory all have to cross deliberately rather than simply being available.
Why this comes up
The problem
Flutter was added screen by screen, and the navigation stack now behaves differently depending on which world the user came from.
What you get
What we deliver
- Migration boundaries drawn at whole flows rather than individual screens
- Navigation ownership decided, so one side controls the stack rather than both
- Shared state passed explicitly across the boundary, not assumed available
- Memory considered, since running both adds overhead while the migration lasts
- Design reconciled, so the two halves do not look like different applications
- The native code actually removed as each flow is replaced

Flutter Migration in Bristol — common questions
- Can we migrate one screen at a time?
- Technically yes, and it usually produces a poor result. Users notice transitions between the two worlds, and navigation becomes complicated when both halves want to manage it — migrating a complete flow at a time keeps each boundary crossing rare and predictable.
- Who should own navigation?
- One side, chosen deliberately. Splitting it produces back-button behaviour that differs by route and is very difficult to reason about — the host application usually keeps control until enough has been migrated to hand it over entirely.
- What is the cost while both run?
- Memory and application size, plus two sets of skills on the team. That is acceptable for a defined migration period and expensive as a permanent arrangement, which is why finishing matters more than starting well.
- How do we avoid stalling halfway?
- Remove the native implementation as each flow is replaced, and treat the last awkward screens as part of the project. Migrations stop when the visible benefit has been captured, and running both indefinitely is worse than either alone.
- Do you work with businesses across Bristol?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Bristol and the surrounding Bristol area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Bristol businesses do you usually work with?
- Engineering-grade requirements from aerospace clients, and brand-led digital work from the creative and environmental sectors. Beyond that we work across Aerospace, Creative & Media, Technology, Financial Services and Environmental.
- Do you cover the areas around Bristol?
- Yes — we work throughout South West, including Cardiff, Bath, Southampton. Bristol is an urban area of roughly 700,000+, and we take on work across the wider Bristol region rather than the city boundary alone.
