throws_plugin 1.0.0-alpha.8

Analyzer plugin for @Throws/@throws usage.

throws_plugin

Analyzer plugin for @Throws/@throws usage.

Install

Add the plugin dependency to your pubspec.yaml and enable it in analysis_options.yaml.

analysis_options.yaml:

plugins:
  throws_plugin:
    version: any
    diagnostics:
      missing_throws_annotation: error
      throws_annotation_mismatch: error
      unused_throws_annotation: error
      introduced_throws_in_override: error
      missing_error_handling: error

Lints

• missing_throws_annotation: functions that throw must be annotated with @Throws/@throws
• unhandled_throws_call: calls to throwing functions must be handled or annotated
• unused_throws_annotation: @Throws on functions that do not throw

Diagnostics are reported at the call site for unhandled throws.

Assists

• Add @Throws annotation
• Remove@Throws annotation
• Wrap in try/catch (with inferred errors when available)

throws.yaml

Place throws.yaml at the package root to extend or override known throwing members.

throws:
  use_sdk_map: true
  map:
    dart:core.Iterable.single:
      - StateError

If useSdkMap is false, only entries from throws.yaml are used. useSdkMap is heuristic only and comes with no guarantees of completeness or accuracy.
