<p>Called when this object is inserted into the tree.</p>
|
|
<p>The framework will call this method exactly once for each <a href="https://api.flutter.dev/flutter/widgets/State-class.html">State</a> object
|
|
it creates.</p>
|
|
<p>Override this method to perform initialization that depends on the
|
|
location at which this object was inserted into the tree (i.e., <a href="https://api.flutter.dev/flutter/widgets/State/context.html">context</a>)
|
|
or on the widget used to configure this object (i.e., <a href="https://api.flutter.dev/flutter/widgets/State/widget.html">widget</a>).</p>
|
|
<p>If a <a href="https://api.flutter.dev/flutter/widgets/State-class.html">State</a>'s <a href="../../pages_transfer_screen/TransferScreenState/build.html">build</a> method depends on an object that can itself
|
|
change state, for example a <a href="https://api.flutter.dev/flutter/foundation/ChangeNotifier-class.html">ChangeNotifier</a> or <a href="https://api.flutter.dev/flutter/dart-async/Stream-class.html">Stream</a>, or some
|
|
other object to which one can subscribe to receive notifications, then
|
|
be sure to subscribe and unsubscribe properly in <a href="../../pages_transfer_screen/TransferScreenState/initState.html">initState</a>,
|
|
<a href="https://api.flutter.dev/flutter/widgets/State/didUpdateWidget.html">didUpdateWidget</a>, and <a href="https://api.flutter.dev/flutter/widgets/State/dispose.html">dispose</a>:</p>
|
|
<ul>
|
|
<li>In <a href="../../pages_transfer_screen/TransferScreenState/initState.html">initState</a>, subscribe to the object.</li>
|
|
<li>In <a href="https://api.flutter.dev/flutter/widgets/State/didUpdateWidget.html">didUpdateWidget</a> unsubscribe from the old object and subscribe
|
|
to the new one if the updated widget configuration requires
|
|
replacing the object.</li>
|
|
<li>In <a href="https://api.flutter.dev/flutter/widgets/State/dispose.html">dispose</a>, unsubscribe from the object.</li>
|
|
</ul>
|
|
<p>You should not use <a href="https://api.flutter.dev/flutter/widgets/BuildContext/dependOnInheritedWidgetOfExactType.html">BuildContext.dependOnInheritedWidgetOfExactType</a> from this
|
|
method. However, <a href="https://api.flutter.dev/flutter/widgets/State/didChangeDependencies.html">didChangeDependencies</a> will be called immediately
|
|
following this method, and <a href="https://api.flutter.dev/flutter/widgets/BuildContext/dependOnInheritedWidgetOfExactType.html">BuildContext.dependOnInheritedWidgetOfExactType</a> can
|
|
be used there.</p>
|
|
<p>Implementations of this method should start with a call to the inherited
|
|
method, as in <code>super.initState()</code>.</p>
