Flutter Developer: Hard Skills
8 categories to include in your resume's Technical Skills section
Stars flag the must-haves. The closing line on each card drops straight into the matching row of your
Skills section, no reshaping needed.
The language at the bottom of every Flutter file. Dart 3 with sound null safety
is the baseline; records, patterns, and sealed classes lift a Mid file toward Senior; extension
methods, isolates for compute-heavy work, and FFI for native interop separate Senior from Staff.

The widgets, build context, and rendering primitives every Flutter file rests on.
Flutter 3.24+ with the widgets tree, BuildContext discipline, keys, and Material 3 plus Cupertino is
the working baseline; flutter_hooks, custom RenderObjects, and a clean SliverList story move the file
toward Senior.

Where Flutter files split fastest. Riverpod 2 reads as declarative-first;
BLoC and Cubit own event-driven enterprise files; Provider stays the legacy fallback; GetX and MobX
still appear on older codebases. State restoration plus declarative side effects round out the
Senior signal.

The routing layer screens hit first. go_router is the working default on
greenfield; auto_route keeps a strong following for type-safe routes with code generation; deep links,
web URL handling, and nested navigators show the file has shipped beyond a single tab bar.

Where shipped Flutter work proves itself. dio, http, and retrofit own the
network row; sqflite, Drift, Isar, Hive, and Realm split the local-database row; secure storage,
the Firebase suite, and GraphQL through Ferry or graphql_flutter close out the data story.

Where shipping discipline gets graded. Flutter SDK channels, melos on monorepos,
Codemagic or Fastlane for the CI pipeline, the FlutterFire CLI for Firebase wiring, build_runner with
freezed and json_serializable for code generation, and Skia or Impeller on the renderer row keep the
Senior file honest.

The line where shipped Flutter work becomes maintained Flutter work. flutter_test
with widget tests reads as modern; integration_test plus Patrol split the E2E row on 2026 files;
Mocktail handles mocks; golden tests via golden_toolkit close the design-system loop; BLoC tests keep
the state layer honest.

The track that turns shipped Dart into a real store release. Play Store and
App Store with App Bundle on the distribution row, Shorebird OTA on the hotfix row, Flutter Web and
Flutter Desktop on the multi-target row, platform channels and FFI on the native-interop row. This
is where Staff Flutter candidates own the path, not only the feature.
