diagnostic_describe_all_properties

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

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.

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

import 'package:flutter/material.dart';
​
class const C({super.key}) extends Widget {
  bool get p1 => true;
​
  bool get p2 => false;
​
  @override
  void debugFillProperties(DiagnosticPropertiesBuilder properties) {
    super.debugFillProperties(properties);
    properties.add(DiagnosticsProperty<bool>('p1', p1));
  }
}

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:

import 'package:flutter/material.dart';
​
class const C({super.key}) 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));
  }
}
