Many companies know they need to modernize, but don’t know where to start. No clear plan, no alignment, just rising costs and slow progress. We’ve seen this scenario play out across industries, and after guiding dozens of teams through it, we saw a clear gap. This guide was created in response to a real market need – to bring structure, clarity, and real business outcomes to Flutter migration.

Most teams don’t hesitate because they doubt Flutter, they hesitate because they don’t know how to migrate without breaking things. After working closely with many teams through real migrations, I can say this: the challenges around architecture, team setup, and native integration can be solved – with the right structure. This guide draws on our experience across multiple projects and shows you how to approach migration the right way.
