automap 0.1.0

A lightweight object mapper for Dart, with support for automatic JSON-based mapping and manual mapping expressions.

Changelog

0.1.0 - 2026-08-14

Note: this release drops support for Dart 2 and contains breaking changes.

Breaking changes

• Require Dart 3 (sdk: ^3.0.0).
• Rename MapDoesNotExistError to MapDoesNotExistException and MapDuplicateError to MapDuplicateException; every exception now extends the new sealed AutoMapperException base class.
• AutoMapper now has a private constructor: use the AutoMapper.I singleton, or AutoMapper.reset() to get a fresh instance.
• Manual map expressions now receive Map<String, dynamic> params instead of a raw Map.
• MapException now exposes message, cause and stackTrace fields.
• AutoMapperModel is now an abstract interface class.

Features

• Add AutoMapper.reset() to replace the singleton instance, useful to isolate state between tests.
• Deprecate addMap in favor of addAutoMap (kept as a delegating alias).
• Wrap failures thrown by mapping expressions in MapException, preserving the original cause and stack trace; programming errors (Error) are no longer masked and propagate untouched.
• Validate the result of mapping expressions and throw a descriptive MapException instead of failing with an opaque cast error.
• Throw a descriptive MapDoesNotExistException when an auto map exists but the source does not implement AutoMapperModel.

Maintenance

• Migrate from the discontinued lint package to package:lints with strict-casts, strict-raw-types and strict-inference.
• Add a full test suite and GitHub Actions CI and release workflows.
• Remove the stale Flutter .metadata artifact.
