      <p>Add additional properties associated with the node.</p>
<p>Use the most specific <code>DiagnosticsProperty</code> existing subclass to describe
each property instead of the <code>DiagnosticsProperty</code> base class. There are
only a small number of <code>DiagnosticsProperty</code> subclasses each covering a
common use case. Consider what values a property is relevant for users
debugging as users debugging large trees are overloaded with information.
Common named parameters in <code>DiagnosticsNode</code> subclasses help filter when
and how properties are displayed.</p>
<p><code>defaultValue</code>, <code>showName</code>, <code>showSeparator</code>, and <code>level</code> keep string
representations of diagnostics terse and hide properties when they are not
very useful.</p><ul><li>Use <code>defaultValue</code> any time the default value of a property is
uninteresting. For example, specify a default value of null any time
a property being null does not indicate an error.</li><li>Avoid specifying the <code>level</code> parameter unless the result you want
cannot be achieved by using the <code>defaultValue</code> parameter or using
the <code>ObjectFlagProperty</code> class to conditionally display the property
as a flag.</li><li>Specify <code>showName</code> and <code>showSeparator</code> in rare cases where the string
output would look clumsy if they were not set.
<pre class="language-dart"><code class="language-dart">DiagnosticsProperty&lt;Object&gt;('child(3, 4)', null, ifNull: 'is null', showSeparator: false).toString()
</code></pre>Shows using <code>showSeparator</code> to get output <code>child(3, 4) is null</code> which
is more polished than <code>child(3, 4): is null</code>.
<pre class="language-dart"><code class="language-dart">DiagnosticsProperty&lt;IconData&gt;('icon', icon, ifNull: '&lt;empty&gt;', showName: false)).toString()
</code></pre>Shows using <code>showName</code> to omit the property name as in this context the
property name does not add useful information.</li></ul>
<p><code>ifNull</code>, <code>ifEmpty</code>, <code>unit</code>, and <code>tooltip</code> make property
descriptions clearer. The examples in the code sample below illustrate
good uses of all of these parameters.</p>
<h2 id="diagnosticsproperty-subclasses-for-primitive-types">DiagnosticsProperty subclasses for primitive types</h2><ul><li><code>StringProperty</code>, which supports automatically enclosing a <code>String</code>
value in quotes.</li><li><code>DoubleProperty</code>, which supports specifying a unit of measurement for
a <code>double</code> value.</li><li><code>PercentProperty</code>, which clamps a <code>double</code> to between 0 and 1 and
formats it as a percentage.</li><li><code>IntProperty</code>, which supports specifying a unit of measurement for an
<code>int</code> value.</li><li><code>FlagProperty</code>, which formats a <code>bool</code> value as one or more flags.
Depending on the use case it is better to format a bool as
<code>DiagnosticsProperty&lt;bool&gt;</code> instead of using <code>FlagProperty</code> as the
output is more verbose but unambiguous.</li></ul>
<h2 id="other-important-diagnosticsproperty-variants">Other important <code>DiagnosticsProperty</code> variants</h2><ul><li><code>EnumProperty</code>, which provides terse descriptions of enum values
working around limitations of the <code>toString</code> implementation for Dart
enum types.</li><li><code>IterableProperty</code>, which handles iterable values with display
customizable depending on the <code>DiagnosticsTreeStyle</code> used.</li><li><code>ObjectFlagProperty</code>, which provides terse descriptions of whether a
property value is present or not. For example, whether an <code>onClick</code>
callback is specified or an animation is in progress.</li></ul>
<p>If none of these subclasses apply, use the <code>DiagnosticsProperty</code>
constructor or in rare cases create your own <code>DiagnosticsProperty</code>
subclass as in the case for <code>TransformProperty</code> which handles <code>Matrix4</code>
that represent transforms. Generally any property value with a good
<code>toString</code> method implementation works fine using <code>DiagnosticsProperty</code>
directly.</p>
