Define and generate mock objects for external dependencies using `package:mockito` and `build_runner`. Use when unit testing classes that depend on complex external services like APIs or databases.
Code Generation Guidelines
Code Generation Guidelines
Runs the deterministic build_runner codegen pass (drift_dev, freezed, json_serializable, riverpod_generator) as one pinned command with --delete-conflicting-outputs, always before flutter analyze, never hand-editing or force-committing generated *.g.dart / *.freezed.dart / *.drift.dart output, watch only in local dev. Use when regenerating codegen, fixing "missing part file" / "conflicting outputs" / undefined generated-class analyzer errors, after editing a drift table or DAO, a freezed value object, a riverpod Notifier or provider, or a json_serializable model, or after a fresh git clone, branch switch, or pull.
Enforces a deterministic build_runner codegen discipline: run one pinned `dart run build_runner build --delete-conflicting-outputs` pass BEFORE `flutter analyze` (never after), fence every builder with `generate_for:` globs in a per-package `build.yaml`, make one deliberate commit-vs-gitignore decision for `*.g.dart`/`*.freezed.dart`/`*.drift.dart` and back it with the matching CI gate (freshness diff if committed, codegen-first if gitignored), mirror the generated-file globs into the analyzer AND coverage excludes, pin the SDK, and never hand-edit generated output. Use when editing build.yaml, analysis_options.yaml, pubspec.yaml, .gitignore, .gitattributes, or CI workflows; wiring drift_dev/freezed/json_serializable/riverpod_generator/ gen-l10n/mockito codegen; fixing "missing part file", "undefined class _$Foo", or "conflicting outputs" errors; deciding whether to commit generated code; or scoping builders so one edit does not regenerate everything.
