createState method

@override _PostCardMedia createState()

Creates the mutable state for this widget at a given location in the tree.

Subclasses should override this method to return a newly created instance of their associated State subclass:

@override
State<SomeWidget> createState() => _SomeWidgetState();

The framework can call this method multiple times over the lifetime of a StatefulWidget. For example, if the widget is inserted into the tree in multiple locations, the framework will create a separate State object for each location. Similarly, if the widget is removed from the tree and later inserted into the tree again, the framework will call createState again to create a fresh State object, simplifying the lifecycle of State objects.

Implementation

@override
_PostCardMedia createState() => _PostCardMedia(
    mediaList: mediaList,
    // downloadButtonKey: downloadButtonKey,
    onFullPage: onFullPage,
    totalItems: totalItems,
    pageNumber: pageNumber,
    onItemClick: onItemClick,
    onPositionChange: onPositionChange,
    pagePosition: pagePosition,
    isLocalFile: isLocalFile);
