+# [Whatsapp Share Plugin](https://pub.dev/packages/whatsapp_share)
+
+[![pub package](https://img.shields.io/pub/v/whatsapp_share.svg)](https://pub.dartlang.org/packages/flutter_share)
+
+
+A Flutter plugin for Android providing a simple way to share a message, link or local files to specific WhatsApp contact.
+
+## Features:
+
+* Share messages or link urls to specific contact.
+* Share local files to specific contact.
+
+
+## Installation
+
+First, add this to your package's pubspec.yaml file:
+```
+dependencies:
+  whatsapp_share: ^1.1.1
+```
+
+Now in your Dart code, you can use:
+```
+import 'package:whatsapp_share/whatsapp_share.dart';
+```
+## Installation (Platform Specific)
+
+### iOS
+
+Add if not exists one row to the `ios/podfile` after target runner:
+
+```
+...
+
+target 'Runner' do
+    use_frameworks!
+
+...
+```
+
+### Android
+
+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>
+```
+
+If you want to learn more about file provider you can access:
+
+  - https://developer.android.com/reference/android/support/v4/content/FileProvider
+
+## How to use?
+
+Here is an snippets app displaying the two whatsapp share methods .
+
+### Whatsapp installed in this device ?
+
+```Dart
+ Future<void> isInstalled() async {
+    final val = await WhatsappShare.isInstalled(
+      package: Package.businessWhatsapp
+    );
+    print('Whatsapp Business is installed: $val');
+  }
+```
+<small>If whatsapp is not installed, please do not call ```WhatsappShare.share()``` and ```WhatsappShare.shareFile()```
+</small>
+
+
+### Share text, links
+
+```Dart
+
+ Future<void> share() async {
+    await WhatsappShare.share(
+      text: 'Whatsapp share text',
+      linkUrl: 'https://flutter.dev/',
+      phone: '911234567890',
+    );
+  }
+
+```
+
+### Share images, files
+
+```_image1.path``` contains path of the file which is shared to the whatsapp.
+
+```Dart
+
+ Future<void> shareFile() async {
+    await WhatsappShare.shareFile(
+      phone: '911234567890',
+      filePath: [_image1.path, _image2.path],
+    );
+  }
+
+```
