<p>Describes the part of the user interface represented by this widget.</p>
|
|
<p>The framework calls this method when this widget is inserted into the tree
|
|
in a given <a href="https://api.flutter.dev/flutter/widgets/BuildContext-class.html">BuildContext</a> and when the dependencies of this widget change
|
|
(e.g., an <a href="https://api.flutter.dev/flutter/widgets/InheritedWidget-class.html">InheritedWidget</a> referenced by this widget changes). This
|
|
method can potentially be called in every frame and should not have any side
|
|
effects beyond building a widget.</p>
|
|
<p>The framework replaces the subtree below this widget with the widget
|
|
returned by this method, either by updating the existing subtree or by
|
|
removing the subtree and inflating a new subtree, depending on whether the
|
|
widget returned by this method can update the root of the existing
|
|
subtree, as determined by calling <a href="https://api.flutter.dev/flutter/widgets/Widget/canUpdate.html">Widget.canUpdate</a>.</p>
|
|
<p>Typically implementations return a newly created constellation of widgets
|
|
that are configured with information from this widget's constructor and
|
|
from the given <a href="https://api.flutter.dev/flutter/widgets/BuildContext-class.html">BuildContext</a>.</p>
|
|
<p>The given <a href="https://api.flutter.dev/flutter/widgets/BuildContext-class.html">BuildContext</a> contains information about the location in the
|
|
tree at which this widget is being built. For example, the context
|
|
provides the set of inherited widgets for this location in the tree. A
|
|
given widget might be built with multiple different <a href="https://api.flutter.dev/flutter/widgets/BuildContext-class.html">BuildContext</a>
|
|
arguments over time if the widget is moved around the tree or if the
|
|
widget is inserted into the tree in multiple places at once.</p>
|
|
<p>The implementation of this method must only depend on:</p>
|
|
<ul>
|
|
<li>the fields of the widget, which themselves must not change over time,
|
|
and</li>
|
|
<li>any ambient state obtained from the <code>context</code> using
|
|
<a href="https://api.flutter.dev/flutter/widgets/BuildContext/dependOnInheritedWidgetOfExactType.html">BuildContext.dependOnInheritedWidgetOfExactType</a>.</li>
|
|
</ul>
|
|
<p>If a widget's <a href="../../app/McgApp/build.html">build</a> method is to depend on anything else, use a
|
|
<a href="https://api.flutter.dev/flutter/widgets/StatefulWidget-class.html">StatefulWidget</a> instead.</p>
|
|
<p>See also:</p>
|
|
<ul>
|
|
<li><a href="https://api.flutter.dev/flutter/widgets/StatelessWidget-class.html">StatelessWidget</a>, which contains the discussion on performance considerations.</li>
