A Flutter plugin for IOS and Android providing a simple way to share a message, link or local files.
First, add flutter_share as a dependency in your pubspec.yaml file.
Add if not exists one row to the ios/podfile after target runner:
...
target 'Runner' do
use_frameworks!
...
If you pretends to use the file share, you need to configure the file provider, this will give access to the files turning possible to share with other applications.
Add to AndroidManifest.xml:
<application>
...
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
</application>
Obs: You can change the android:name if you have an extension of file provider.
Add res/xml/provider_paths.xml:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>

Here is an example flutter app displaying the two shares methods. (I'm using documents_picker just to get a local file you don't need to use.)
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:flutter_share/flutter_share.dart';
import 'package:documents_picker/documents_picker.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
Future<void> share() async {
await FlutterShare.share(
title: 'Example share',
text: 'Example share text',
linkUrl: 'https://flutter.dev/',
chooserTitle: 'Example Chooser Title'
);
}
Future<void> shareFile() async {
List<dynamic> docs = await DocumentsPicker.pickDocuments;
if (docs == null || docs.isEmpty) return null;
await FlutterShare.shareFile(
title: 'Example share',
text: 'Example share text',
filePath: docs[0] as String,
);
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
FlatButton(
child: Text('Share text and link'),
onPressed: share,
),
FlatButton(
child: Text('Share local file'),
onPressed: shareFile,
),
],
),
),
),
);
}
}
