5.0.0

• Bump minimum Dart SDK version to 2.12.0
• Migration to null safety

4.0.3

• Remove usages of .slice to help downstream packages work around a dart2js compiler bug

4.0.2

• Fix bug where type getter would throw when typeList was null

4.0.1

• Performance:
  • cache calls to resolvePath
  • JsonSchema.schemaMap is now truly unmodifiable (was before in practice anyway) and hashCode is cached by taking advantage of that.
• 4.0 Release Mistake:
  • Validator.evaluatedProperties was accidentally made public, pull it back to private.

4.0.0

json_schema 4.0 continues our journey to support additional new versions of the JSON Schema specification (Draft 2019-09 and Draft 2020-12)! Custom vocabulary and format support is also included in this release! In addition to those major features, we have better support for certain built-in formats, as well as improved spec test compliance.

We have greatly reduced the number of dependencies in preparation for a null-safety release (which we're planning in another major release). This has also come with a new Makefile instead our old dart_dev based commands (see README).

• Additions:
  • Support for JSON Schema Draft 2019-09 (SchemaVersion.draft2019_09)
  • Support for JSON Schema Draft 2020-12 (SchemaVersion.draft2020_12)
  • Default draft is still draft7 for compatibility.
  • Custom Keywords:
    • List<CustomVocabulary> customVocabularies can be passed to all JsonSchema factories.
    • CustomVocabulary
    • CustomKeyword
    • ValidationContext
  • Custom Formats:
    • Map<String, Function> customFormats can be passed to and JsonSchema factory.
    • ValidationContext
• Deprecated:
  • validateWithResults in favor of validate which now returns the same thing (ValidationResults).
  • DefaultValidators and related globals in favor of passing customFormats to the JsonSchema factories.
• Removed Deprecations:
  • Removed bin/schemadot.dart, lib/schema_dot.dart and related examples
  • Removed lib/browser.dart and lib/vm.dart and associated globals createSchemaFromUrlBrowser, configureJsonSchemaForBrowser, globalCreateJsonSchemaFromUrl createSchemaFromUrlVm, configureJsonSchemaForVm and resetGlobalTransportPlatform. These were for configuring the runtime environment, which now happens automatically.
  • Removed JsonSchema.createSchemaAsync in favor of JsonSchema.createAsync
  • Removed JsonSchema.createSchema in favor of JsonSchema.create
  • Removed JsonSchema.createSchemaFromUrl in favor of JsonSchema.createFromUrl
  • Removed RefProvider.asyncSchema, RefProvider.syncSchema, RefProvider.asyncJson, and RefProvider.syncJson in favor of RefProvider.async and RefProvider.async, which are easier to use.
  • Removed JsonSchema.refMap
• Breaking change to validate:
  • now returns ValidationResult instead of bool like validateWithResults (now deprecated).
• Notable change of behavior to resolvePath with 2019-09 and 2020-12:
  • When used with draft 2019-09 or draft 2020-12, $refs alongside other keywords, which wasn't allowed in earlier drafts, can't always be resolved. We make a best-effort to resolve authoritatively and fall back to throwing an error if the resolution is ambiguous. In future releases, we may release support for resolving this sort of ambiguity (properties + ref, sub-property of a $ref and as sub-property conflicting, etc) based on user-preference.
  • $dynamicRefs cannot yet be resolved using this method (you will only receive the ref itself.)
