Walkthrough

This update refactors authentication and Trezor initialization state classes to use the Freezed package for immutable data classes, adds generated Freezed files, updates dependencies and analyzer settings, adjusts index generator configurations to exclude Freezed files, and expands the types library export list.

Poem

In fields of code where Freezed winds blow,
Old boilerplate now melts like snow.
State classes trimmed, equality neat,
With copyWith magic, updates repeat.
A hop, a skip, dependencies grow—
The garden of types begins to show!
🐇✨

🔇 Additional comments (14)

packages/komodo_defi_rpc_methods/index_generator.yaml (1)

8-8: Exclude .freezed.dart files from index generation
Pattern addition aligns with existing .g.dart exclusion to keep generated boilerplate out of index files.

packages/komodo_defi_local_auth/pubspec.yaml (2)

29-29: Add freezed_annotation to dependencies
Enables use of @freezed annotation in the package for immutable data classes.

---

36-37: Add build_runner and freezed to dev_dependencies
Supports code generation for freezed models; versions are consistent with freezed_annotation.

packages/komodo_defi_types/analysis_options.yaml (1)

4-4: Suppress invalid_annotation_target analyzer warning
Prevents spurious errors when using code generation annotations (e.g., @freezed).

packages/komodo_defi_sdk/index_generator.yaml (1)

8-8: Exclude .freezed.dart files from index generation
Keeps generated .freezed.dart files out of the public index, mirroring other packages.

packages/komodo_defi_types/lib/src/types.dart (1)

48-48: Export seed_node/seed_node.dart in types.dart
Exposes the new SeedNode module in the public API surface; placement respects alphabetical grouping.

packages/komodo_defi_local_auth/lib/src/auth/auth_state.dart (3)

1-4: Excellent refactoring to freezed!

The migration from manual Equatable implementation to freezed is well-executed. The import change and part directive are correctly placed.

---

7-15: Clean freezed class definition.

The @freezed annotation and factory constructor properly replace the manual boilerplate while maintaining all original fields and their types.

---

17-22: Factory constructors preserved correctly.

The named factory constructors completed and error maintain the existing public API, ensuring backward compatibility.

packages/komodo_defi_local_auth/lib/src/trezor/trezor_initialization_state.freezed.dart (1)

1-155: Generated freezed file looks correct.

This auto-generated file follows standard freezed patterns with proper equality, copyWith methods, and immutability. No manual modifications needed.

packages/komodo_defi_local_auth/lib/src/trezor/trezor_initialization_state.dart (3)

1-5: Proper freezed setup.

Import changes and part directive are correctly implemented for the freezed migration.

---

8-18: Well-structured freezed class with private constructor.

The @freezed annotation, factory constructor, and private constructor TrezorInitializationState._() are properly set up to support the custom factory methods below.

---

20-154: Factory methods and business logic preserved.

All the complex factory methods (fromStatusResponse, fromInProgressDescription, fromUserActionRequired) and the toAuthenticationState() conversion method are correctly maintained, ensuring no functionality is lost in the refactoring.

packages/komodo_defi_local_auth/lib/src/auth/auth_state.freezed.dart (1)

1-155: Standard freezed generation looks correct.

This auto-generated file provides all the expected freezed functionality including immutability, value equality, and copyWith methods. No manual changes required.

• Ignoring invalid_annotation_target globally may suppress legitimate errors in hand-written code; consider scoping this ignore to generated files only.
