Lint rule

The public property isn't described by either 'debugFillProperties' or 'debugDescribeChildren'.

Description

#

The analyzer produces this diagnostic when a class that implements Diagnosticable has a public property that isn't added as a property in either a debugFillProperties or debugDescribeChildren method.

Example

#

The following code produces this diagnostic because the property p2 isn't added in the debugFillProperties method:

dart
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';

class C extends Widget {
  bool get p1 => true;

  bool get p2 => false;

  @override
  void debugFillProperties(DiagnosticPropertiesBuilder properties) {
    super.debugFillProperties(properties);
    properties.add(DiagnosticsProperty<bool>('p1', p1));
  }
}

Common fixes

#

If there isn't on override of either the debugFillProperties or debugDescribeChildren method, then add one.

Add a description of the property in the debugFillProperties or debugDescribeChildren method:

dart
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';

class C extends Widget {
  bool get p1 => true;

  bool get p2 => false;

  @override
  void debugFillProperties(DiagnosticPropertiesBuilder properties) {
    super.debugFillProperties(properties);
    properties.add(DiagnosticsProperty<bool>('p1', p1));
    properties.add(DiagnosticsProperty<bool>('p2', p2));
  }
}
