Output example


Use --reporter=console to enable this format.



The reporter prints a single JSON object containing meta information and the incomplete exports. Use --reporter=json to enable this format.

The root object fields are

  • formatVersion - an integer representing the format version (will be incremented each time the serialization format changes)
  • timestamp - a creation time of the report in YYYY-MM-DD HH:MM:SS format
  • incompleteExports - an array of incomplete exports issues
"formatVersion": 2,
"timestamp": "2021-04-11 14:44:42",
"incompleteExports": [

The incompleteExports object fields are

  • path - a relative path of the file with the declaration that needs to be exported
  • issues - an array of issues detected in the target class
"path": "lib/src/some/class.dart",
"issues": [

The issue object fields are

  • referencePath - the path representing the call chain from the entrypoint to this declaration
  • declarationName - the name of a declaration that needs to be exported
  • declarationType - the type of a declaration that needs to be exported (function, method or constructor)
  • offset - a zero-based offset of the class member location in the source
  • line - a zero-based line of the class member location in the source
  • column - a zero-based column of class member the location in the source
"referencePath": "entrypoint > someClass",
"declarationName": "someFunction",
"declarationType": "function",
"offset": 156,
"line": 7,
"column": 1


Reports export issues in merge requests based on Code Quality custom tool. Use --reporter=gitlab to enable this format.
