FAQ
Questions teams usually ask
How much does it cost to hire a Flutter developer?
Cost depends on scope, complexity, integrations and engagement model. After a short discovery call, Solvinex provides a clear recommendation and estimate without publishing a misleading one-size-fits-all price.
Can I hire a Flutter developer for an existing project?
Yes. We can audit the current codebase, stabilise urgent issues and agree a practical roadmap before feature development begins.
Can your developer work with our existing team?
Yes. We can work within your tools, sprint rhythm, review process and communication channels while keeping ownership and progress visible.
Do you offer dedicated Flutter developers?
Yes. Dedicated, flexible hourly and fixed project models are available, depending on the continuity and certainty your roadmap needs.
Can you handle migration?
Yes. We assess existing native or cross-platform apps and plan a staged Flutter migration around feature parity and store continuity.
Do you provide maintenance after launch?
Yes. Support can include monitoring, upgrades, fixes, performance improvements and an ongoing product roadmap.
