# Hire a Flutter developer for your app > Hire a Flutter developer when you want one polished app for iPhone and Android and care about a consistent look and smooth animation on both. Canonical: https://erdibuilds.app/hire/flutter Last updated: 2026-11-06 (November 6, 2026) ## How Flutter is different Flutter is Google's toolkit for building apps. Instead of using the phone's built-in buttons, it draws every pixel itself. The result looks the same on every device, which is great for apps with a strong custom design, animations or unusual layouts. Developers write Flutter apps in Dart (A programming language made by Google. It is easy to read and is used almost only for Flutter.). That keeps one codebase for both stores. Typical fits are branded [mobile apps](https://erdibuilds.app/build/mobile-app), apps with rich visuals, [mobile games](https://erdibuilds.app/build/mobile-game) that are light on 3D, and companion apps for devices or services. The trade-off is a smaller pool of Flutter specialists than for some other tools. If your team or a future hire already knows JavaScript, [React Native](https://erdibuilds.app/hire/react-native-expo) may be easier to maintain. ## Questions to ask a Flutter developer - How do you structure the app so it stays easy to change when it grows? - Which state management approach do you use and why? - How do you test the app on older phones? - What do you do when a feature needs a native iPhone or Android call? - How do you handle different screen sizes and tablets? - Which of your published Flutter apps can I download? ## Milestones that make sense A common order for a Flutter app puts the look first, since design is the strength of the tool. Milestones are from 50 to 2,000 each in your project currency. Each is funded before work starts. The weeks in this example are for illustration, and developers set the length of each milestone in their proposal. 1. Design system and key screens (for example, weeks 1 to 2): colours, type, components, first navigation. 2. Data and accounts (for example, weeks 3 to 4): login, backend connection, saving and loading. 3. Main features (for example, weeks 5 to 7): the heart of the product, with animations where they help. 4. Testing and release (for example, weeks 8 to 9): device checks, store pages, review, launch. Between phases you approve the delivery or ask for changes. If no one reacts, a milestone is approved automatically after 14 days, so keep an eye on your notifications. ## How developers are matched A developer can mark Flutter as Expert in (One of at most 6 technologies a developer knows best.) or as Also works with (A technology they use but is not their main one.). Your project is scored for the help type, project type, technologies, portfolio, budget fit and availability, from 0 to 100 with plain reasons. Developers need at least 40 to apply. A score of 80 or more shows a Top match badge. You see proposals sorted by score. ## Frequently asked questions ### Flutter or fully native? Flutter saves effort when you need both platforms. Fully native with [Swift](https://erdibuilds.app/hire/swift) or [Kotlin](https://erdibuilds.app/hire/kotlin) fits when you need deep access to one platform's newest features. ### Can Flutter also make a website? It can produce a web version, but it suits app-like pages better than content sites that must rank in search. For those, see [Next.js](https://erdibuilds.app/hire/nextjs). ### Is Flutter good for games? For simple 2D games, yes. For larger games, an engine such as [Unity](https://erdibuilds.app/hire/unity) or [Godot](https://erdibuilds.app/hire/godot) is usually the better tool. ### What backend goes with it? [Firebase](https://erdibuilds.app/hire/firebase) and [Supabase](https://erdibuilds.app/hire/supabase) are both common choices. The developer should explain the pick. ## Related - [Hire a React Native and Expo developer](https://erdibuilds.app/hire/react-native-expo): One codebase for iPhone and Android: what React Native and Expo can do, what to ask a developer, example milestones and how matching works. - [Hire a Firebase developer for your app](https://erdibuilds.app/hire/firebase): Firebase gives apps logins, data and notifications fast.
