social_story_share

Share to Instagram and Facebook Stories, WhatsApp, Telegram, X and SMS from Flutter, using native APIs on iOS and Android.

Sharing to Instagram/Facebook Stories on iOS normally relies on a CocoaPods plugin. This package implements it as a Swift Package instead, so it keeps working on Flutter projects that have migrated to Swift Package Manager without bringing CocoaPods back. A CocoaPods podspec is still included for projects that have not migrated.

Features

• Instagram and Facebook Stories: full-screen background image or video, an optional sticker overlay, gradient background colors, and an attribution link.
• Direct sharing to WhatsApp, Telegram, X/Twitter and SMS with prefilled text.
• The native OS share sheet (text and/or image).
• Copy text or an image to the clipboard.
• Check which of the supported apps are installed.
• iOS ships as a Swift Package; Android bundles its own FileProvider, so there is no per-app setup on Android.

Comparison

Capability	social_story_share	social_share	share_plus
Instagram Story — background image	yes	yes	no
Instagram Story — background video	yes	no	no
Instagram Story — sticker + gradient	yes	partial	no
Facebook Story	yes	yes	no

For general file sharing through the OS share sheet (multiple files, any file type, plus desktop and web), share_plus is the better choice. This package focuses on Stories and direct-to-app sharing, which share_plus does not cover.

Install

dependencies:
  social_story_share: ^0.2.0

import 'package:social_story_share/social_story_share.dart';

Usage

Instagram and Facebook Stories

// Full-screen background image with a tappable attribution link.
await SocialStoryShare.shareToInstagramStory(
  appId: '<YOUR_META_APP_ID>',
  backgroundImagePath: '/path/to/story.png',
  contentUrl: 'https://example.com/deeplink',
);

// Gradient background with a sticker overlay (no full-screen asset).
await SocialStoryShare.shareToFacebookStory(
  appId: '<YOUR_META_APP_ID>',
  stickerImagePath: '/path/to/sticker.png',
  backgroundTopColor: const Color(0xFF00C6FB),
  backgroundBottomColor: const Color(0xFF005BEA),
);

// A background video also works.
await SocialStoryShare.shareToInstagramStory(
  appId: '<YOUR_META_APP_ID>',
  backgroundVideoPath: '/path/to/story.mp4',
);

Handle the result to fall back when the app is missing:

final result = await SocialStoryShare.shareToInstagramStory(
  appId: '<YOUR_META_APP_ID>',
  backgroundImagePath: '/path/to/story.png',
);

if (result == ShareResult.appNotInstalled) {
  await SocialStoryShare.shareToSystem(imagePath: '/path/to/story.png');
}

Direct text and link sharing

await SocialStoryShare.shareToWhatsApp(text: 'Check this out', phone: '905551112233');
await SocialStoryShare.shareToTelegram(text: 'Check this out', url: 'https://example.com');
await SocialStoryShare.shareToTwitter(text: 'Check this out', url: 'https://example.com', hashtags: ['flutter']);
await SocialStoryShare.shareToSms(text: 'Check this out', recipients: ['905551112233']);

System share sheet, clipboard, availability

await SocialStoryShare.shareToSystem(text: 'Check this out', imagePath: '/path/to/image.png');

await SocialStoryShare.copyToClipboard(text: 'copied', imagePath: '/path/to/image.png');

final hasInstagram = await SocialStoryShare.isInstalled(SocialApp.instagram);
final installed = await SocialStoryShare.installedApps(); // Set<SocialApp>

Story parameters

Parameter	Description
appId	Meta/Facebook App ID, used as source_application. Required.
backgroundImagePath	Full-screen background image (recommended 1080x1920).
backgroundVideoPath	Full-screen background video, used when no background image is given.
stickerImagePath	Sticker image overlaid on the story.
backgroundTopColor	Gradient top color, used only when no background asset is given.
backgroundBottomColor	Gradient bottom color.
contentUrl	URL the sticker links back to.

At least one of backgroundImagePath, backgroundVideoPath or stickerImagePath is required.

Result

Each share returns a ShareResult:

Value	Meaning
success	The target app was opened with the content.
appNotInstalled	The target app is not installed.
missingContent	Nothing was provided to share.
error	The share failed, for example an unreadable file.

Setup

iOS

Add the URL schemes you use to ios/Runner/Info.plist:

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>instagram-stories</string>
  <string>facebook-stories</string>
  <string>whatsapp</string>
  <string>tg</string>
  <string>twitter</string>
</array>

For Stories, register your Meta App ID (FacebookAppID) in Info.plist as usual. No CocoaPods step is required.

Android

No setup is required. The plugin declares its own FileProvider and the package-visibility <queries> it needs. Pass files from a directory the app can read, such as the temporary directory from path_provider.

How it works

On iOS, assets are written to UIPasteboard under the com.instagram.sharedSticker.* and com.facebook.sharedSticker.* keys and the instagram-stories:// / facebook-stories:// schemes are opened; the other targets use their URL schemes and the system sheet uses UIActivityViewController. On Android, Stories use the com.instagram.share.ADD_TO_STORY and com.facebook.stories.ADD_TO_STORY intents with assets exposed through the bundled FileProvider; the other targets use ACTION_SEND, ACTION_SENDTO and ACTION_VIEW.
