dartnative_share

The native share sheet for DartNative — share text and files through the system sheet (UIActivityViewController on iOS, ACTION_SEND on Android). One call, both platforms, nothing to configure.

Why you'll like it

• Zero setup — text or files, on both platforms; the plugin bundles its own Android FileProvider and share <queries>, so there's nothing to add to your app.
• Text, files, captions — one file or many, with an optional caption (shows up as the photo/video caption in apps like WhatsApp).
• Familiar — Share.share(), like share_plus.

Highlights

• Share.share(text) — the system share sheet for some text.
• Share.shareFile(path, {mimeType, text}) — share a file with an optional caption.
• Share.shareFiles(paths, {mimeTypes, text}) — share several files at once.
• Share.shareWithResult(text) (and shareFileWithResult / shareFilesWithResult) — resolve with the outcome once the sheet closes: did the user share, via which target, or did they dismiss.

final result = await Share.shareWithResult('Join me: https://…');
if (result.status == ShareResultStatus.success) {
  analytics.log('shared_via', result.raw);
}

dn pub get

  runApp(const MyApp());
}

Quick look

import 'package:dartnative_share/dartnative_share.dart';

Share text:

Share.share('Join with my code ABC123 — https://dartnative.com');

Share a file with a caption (e.g. a photo + caption on WhatsApp):

Share.shareFile('/tmp/photo.jpg', mimeType: 'image/jpeg', text: 'Check this out!');

Share several files at once:

Share.shareFiles(
  ['/tmp/a.jpg', '/tmp/b.mp4'],
  mimeTypes: ['image/jpeg', 'video/mp4'],
  text: 'Trip recap',
);

On iOS the OS infers each file's type from its extension (mimeTypes is accepted for API parity but ignored). On Android files are vended through the plugin's FileProvider.

Platform setup

iOS

No native setup required.

Android

No native setup required — the plugin ships its own FileProvider and share <queries>, merged into your app automatically.

This plugin is open source — read it, copy it, learn from it

Unlike the other official plugins, dartnative_share ships its full source right here. It's the reference implementation for the Build a plugin tutorial: every layer of a dartnative plugin in ~400 lines — the Dart API, FFI symbol loading, the Swift @_cdecl bridge, the Kotlin + JNI bridge, and (in the *WithResult methods) the hot-restart-safe async callback pattern that every plugin with native→Dart callbacks must follow. Start here when writing your own plugin, or when porting one you already maintain.
