PIT Multiple Image Picker

Multiple Image Picker by PIT

A Flutter plugin for iOS and Android for picking multiple images from the image library, and taking new pictures with the camera.

Note: This plugin is still under development, and some APIs might not be available yet. This plugin is inspired from image picker. The iOS version is okay (using ELCImagePickerController), but the android version is still on progress on its Custom Gallery

Installation

First, add pit_multiple_image_picker as a dependency in your pubspec.yaml file.

pit_multiple_image_picker: ^0.0.3

Android

Add these to your app AndroidManifest.xml file.

        <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
        <uses-permission android:name="android.permission.CAMERA"/>
        <activity
            android:name=".CustomPhotoGalleryActivity"
            android:screenOrientation="portrait">
        </activity>

iOS

Since we are using pit_multiple_image_picker as a dependency from this plugin to load paths from gallery and camera, we need the following keys to your Info.plist file, located in <project root>/ios/Runner/Info.plist:

• NSPhotoLibraryUsageDescription - describe why your app needs permission for the photo library. This is called Privacy - Photo Library Usage Description in the visual editor.
• NSCameraUsageDescription - describe why your app needs access to the camera. This is called Privacy - Camera Usage Description in the visual editor.
• NSMicrophoneUsageDescription - describe why your app needs access to the microphone, if you intend to record videos. This is called Privacy - Microphone Usage Description in the visual editor.

              snapshot.data != null) {
            List<File> files = snapshot.data;
            return (files.length == 1)

        });

          FloatingActionButton(
            onPressed: () {
              _pickImages(5); //pick 5 images max
