Use FlutterStoryPresenter to display stories on any screen. It accepts a list of StoryItem, each containing URLs for displaying images, videos, and web pages.

FlutterStoryPresenter(
    controller : FlutterStoryController(),
    items: [
        /// For Image Story Item
        StoryItem(
            url:'https://picsum.photos/1000/1000',
            type: StoryItemType.image,
        ),
        /// For Video Story Item
        StoryItem(
            url:'https://videos.pexels.com/video-files/7297870/7297870-hd_1080_1920_30fps.mp4',
            type: StoryItemType.video,
        ),
        /// For Text Story Item
        StoryItem(
            url:'We won this tournament ... Many more to go',
            type: StoryItemType.text,
        ),
        /// For Web Story Item

            type: StoryItemType.web,
        ),
        /// For Custom Story Item
        StoryItem(
            customWidget: YourOwnBakedStoryWidget(),
            type: StoryItemType.custom,
        ),
    ]
)

FlutterStoryPresenter Properties

Here are some of the properties you may have look for further customisations & callbacks.

/// List of StoryItem objects to display in the story view.
final List<StoryItem> items;

/// Controller for managing the current playing media.
final FlutterStoryController? flutterStoryController;

/// Callback function triggered whenever the story changes or the user navigates to the previous/next story.
final OnStoryChanged? onStoryChanged;

/// Callback function triggered when all items in the list have been played.
final OnCompleted? onCompleted;

/// Callback function triggered when the user taps on the left half of the screen.
final OnLeftTap? onLeftTap;

/// Callback function triggered when the user taps on the right half of the screen.
final OnRightTap? onRightTap;

/// Callback function triggered when user drag downs the storyview.
final OnSlideDown? onSlideDown;

/// Callback function triggered when user starts drag downs the storyview.
final OnSlideStart? onSlideStart;

/// Indicates whether the story view should restart from the beginning after all items have been played.
final bool restartOnCompleted;

/// Index to start playing the story from initially.
final int initialIndex;

/// Configuration and styling options for the story view indicator.
final StoryViewIndicatorConfig? storyViewIndicatorConfig;

/// Callback function to retrieve the VideoPlayerController when it is initialized and ready to play.
final OnVideoLoad? onVideoLoad;

/// Widget to display user profile or other details at the top of the screen.
final Widget? headerWidget;

/// Widget to display text field or other content at the bottom of the screen.
final Widget? footerWidget;

Using FlutterStoryController

FlutterStoryController is a controller class designed to manage the current story displayed on FlutterStoryPresenter. It includes various methods such as play(), pause(), jumpTo(), next(), previous(), mute(), and unMute(), allowing you to control the existing StoryItem.

final storyController = FlutterStoryController();
FlutterStoryPresenter(
    controller : storyController,
    items: [
        /// Story Item goes here
    ]
)
...
/// Somewhere in your code
storyController.pause();
storyController.play();
storyController.next();
storyController.previous();
storyController.jumpTo(2);
storyController.mute();
storyController.unMute();

Using StoryItem

The StoryItem class is used to define the individual items displayed in a FlutterStoryPresenter. Each StoryItem can represent an image, video, text, web content, or a custom widget.

const StoryItem({
  this.url,
  required this.storyItemType,
  this.thumbnail,
  this.isMuteByDefault = false,
  this.duration = const Duration(seconds: 3),
  this.storyItemSource = StoryItemSource.network,
  this.videoConfig,
  this.errorWidget,
  this.imageConfig,
  this.textConfig,
  this.webConfig,
  this.customWidget,
});

Parameters

• url: The URL, file path, or web URL of the story item. Required unless storyItemType is custom.
• storyItemType: The type of story item. Required. It can be an image, video, text, web content, or custom.
• thumbnail: A widget to display as a thumbnail.
• isMuteByDefault: A boolean indicating whether the video should be muted by default. Applicable when storyItemType is video.
• duration: The duration for displaying the widget. Defaults to 3 seconds.
• storyItemSource: The source type of the story item. Defaults to StoryItemSource.network.
• videoConfig: Configuration for video stories.
• errorWidget: A widget to display when an error occurs while loading the view.
• imageConfig: Configuration for image stories.
• textConfig: Configuration for text stories.
• webConfig: Configuration for web stories.
• customWidget: A custom widget to display fully instead of any other view. Required when storyItemType is custom.

  url: 'https://example.com/image.jpg',
