Suppressing the Command
To suppress for an entire file add ignore_for_file: exports to the beginning of a file.
@visibleForTesting Annotation Support
This command does no report types that are used in parameters marked "@visibleForTesting" as they are not expected to be part of the public API.
@internal Annotation Support
Any exported declarations marked @internal is reported by this command as internal declarations are not expected to be exported. To fix these issues, try hiding reported declarations, making them private or removing the @internal annotation.
Output Example
Console (default)
Use --reporter=console to get output in console format.
JSON
Use --reporter=json to get output as a single JSON object containing metadata and the list of incomplete export issues.
Format specification
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 formatincompleteExports- 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 exportedissues- 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 declarationisMarkedInternal- a boolean flag value that indicates declarations marked @internaldeclarationName- the name of a declaration that needs to be exporteddeclarationType- 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 sourceline- a zero-based line of the class member location in the sourcecolumn- a zero-based column of class member the location in the source
{
"referencePath": "entrypoint > someClass",
"isMarkedInternal": false,
"declarationName": "someFunction",
"declarationType": "function",
"offset": 156,
"line": 7,
"column": 1
}
GitLab
Use --reporter=gitlab to get output in a GitLab-compatible format. To learn how to integrate DCM with GitLab, refer to this guide.
Code Climate

Checkstyle
Use --reporter=checkstyle to get output in Checkstyle format.
Output example
<?xml version="1.0"?>
<checkstyle version="10.0">
<file name="../abstract_class.dart">
<error line="0" severity="warning" message="function myFunction is part of the public API and should be exported" source="exports-issue"/>
</file>
<file name="../class_with_factory_constructors.dart">
<error line="0" severity="warning" message="class MyClass is part of the public API and should be exported" source="exports-issue"/>
<error line="0" severity="warning" message="function myFunction is marked as 'internal' but is publicly accessible" source="exports-issue"/>
</file>
</checkstyle>
note
Checkstyle format is supported by Bitbucket. To learn how to integrate DCM with Bitbucket, refer to this guide.
