json_schema 4.0.0-rc.1

Provide support for validating instances against json schema

4.0.0-rc.1

json_schema 4.0 continues our journey to support additional new versions of the JSON Schema specification (Draft 2019-09 and Draft 2020-12)! In addition to the new draft support, we have better support for certain 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).

• Support for JSON Schema Draft 2019-09
• Default Schema version is now 2019-09 (Breaking)
• Deprecated:
  • validateWithResults in favor of validate which now returns the same thing (ValidationResults).
• 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).
