image_and_file_picker_utility 0.0.1

This Flutter package simplifies the process of picking images and files with common utilities.

Introduction

This Flutter package simplifies the process of picking images from both the camera and gallery, with built-in permission handling, image cropping, saving picked camera images, image compression, and file picking functionality. It aims to provide an easy-to-use solution for handling images and files in your Flutter applications.

Features

• Pick images from camera and gallery with permission handling
• Permission handling for camera and storage
• Image cropping functionality
• Save picked camera images to the device
• Image compression for optimized storage usage
• File picking with permission handling

Getting Started

To integrate the package into your Flutter project, follow these steps:

Step 1: Add Dependency

Add the following dependency to your pubspec.yaml file:

dependencies:
image_and_file_picker_utility: ^0.0.1

Then run:

flutter pub get

Step 2: Android Setup

Add Permissions to AndroidManifest.xml:

<uses-permission android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_MEDIA_IMAGES"/>

Add activity to the application tag for crop image:

<application>
<activity
android:name="com.yalantis.ucrop.UCropActivity"
android:exported="true"
android:screenOrientation="portrait"
android:theme="@style/Theme.AppCompat.Light.NoActionBar" />
</application>

Step 3: IOS Setup

Add permission to the Podfile like below:

post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',
        'PERMISSION_CAMERA=1',
        'PERMISSION_PHOTOS=1',
      ]
    end

end
end

Add permission usage to the info.plist file:

<key>NSPhotoLibraryUsageDescription</key>
<string>Our application needs permission to access photos</string>
<key>NSCameraUsageDescription</key>
<string>Our application needs permission to capture photo</string>

Usage

Image:

Image picking with bottom sheet:

await ImagePickerUtil().showImagePickerBottomSheet(
context: context,
isCropImage: true,
savePickedCameraImageToStorage: true,
pickImageImageQuality: 100,
onImageSelection: (File? pickedImage) {}
);

Image picking from camera:

File? file = await getFromCameraWithPermissionCheck(
context: context,
permissionDescriptionText:
"Permission required to access camera",
isCrop: true,
saveCameraImage:
true,);

Image picking from gallery:

File? file = await getFromGalleryWithPermissionCheck(
context: context,
permissionDescriptionText:
'Permission required to access gallery',
isCrop: true,);

Image cropping

File? file = await cropImage(
file: File("path"),
context: context,
);

File:

import 'package:file_picker/file_picker.dart';

final List<File>? pickedFileList =
await FilePickerUtil().getFilePicker(
allowMultiple: true,
allowCompression: true,
fileType: FileType.any,
context: context,
/// When you want to pick specific extensions files then choose type as FileType.custom and pass the extensions using allowedExtensions parameter
// type:FileType.custom,
// allowedExtensions: ['jpg', 'pdf', 'doc'],
);

Permission Handling:

Storage permission:

bool isPermissionGranted = await PermissionHandler().getStoragePermission(
context: context,
permissionDescriptionText:"Permission is required to access files",
)

Camera permission:

bool isPermissionGranted = await PermissionHandler().getCameraPermission(
context: context,
permissionDescriptionText: "Permission required to access camera")

Photos permission (For IOS only):

bool isPermissionGranted = await PermissionHandler().getPhotosPermission(
context: context,
permissionDescriptionText: "Permission required to access photos")

Open settings for denied permission:

await PermissionHandler().openSettings();
