Getting started

Let's take a look at how to implement EditableImage to fastly create user interfaces for profile picture edit, etc.

Firstly, add following line to pubspec.yaml:

editable_image: ^1.1.0

Second, import EditableImage:

import 'package:editable_image/editable_image.dart';

Lastly, make platform-specific setups by applying the following instructions.

Android Setup

  • The minimum required SDK version is 21. Therefore, please find the following line inside android/app/build.gradle and modify it:
minSdkVersion 21
  • Please upgrade the Kotlin version (ext.kotlin_version) to 1.5.21 or the latest version. To do that, find the following line inside android/build.gradle and modify it:
ext.kotlin_version = '1.5.21'
  • Please upgrade the Gradle version (ext.kotlin_version) to 6.8.3 or the latest version but lower than 7.0.0. To do that, find the following line inside android/gradle/wrapper/gradle-wrapper.properties and modify it:
distributionUrl=https\://services.gradle.org/distributions/gradle-6.8.3-all.zip
  • Please go to your project folder and add android:exported="true" to AndroidManifest.xml file
<activity
     android:name=".MainActivity"
     android:exported="true"
     android:launchMode="singleTop"
     android:theme="@style/LaunchTheme"
 </activity>
  • Required permissions: READ_EXTERNAL_STORAGE. Please modify android/app/src/main/AndroidManifest.xml and update accordingly:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
  • I recommand you add android:requestLegacyExternalStorage="true" to AndroidManifest.xml. Therefore, please modify android/app/src/main/AndroidManifest.xml and add the following line inside application:
<application android:requestLegacyExternalStorage="true" </application>

If you found some warning logs with Glide appearing, then the main project needs an implementation of AppGlideModule. See Generated API.

iOS Setup

  • Platform version must be at least 9.0. Please modify ios/Podfile and update accordingly:
platform :ios, '9.0'
  • Add the following lines to ios/Runner/Info.plist:
<key>NSPhotoLibraryUsageDescription</key>
<string>Put here your permission description.</string>

macOS Setup

  • Platform version must be at least 10.15. Please modify macos/Podfile and update accordingly:
platform :osx, '10.15'
  • Please set the minimum deployment target to 10.15. Use XCode to open macos/Runner.xcworkspace:

  • Follow the iOS instructions and modify ios/Runner/Info.plist accordingly.

 

Usage

Basic usage example:

main.dart

// A simple usage of EditableImage.
// This method gets called when trying to change an image.
void _directUpdateImage(File? file) async {
    if (file == null) return;

    _profilePicFile = file;
    setState(() {});
}

EditableImage(
// Define the method that will run on the change process of the image.
onChange: (file) => _directUpdateImage(file),

// Define the source of the image.
image: _profilePicFile.existsSync()
    ? Image.file(_profilePicFile, fit: BoxFit.cover)
    : null,

// Define the size of EditableImage.
size: 150.0,

// Define the Theme of image picker.
imagePickerTheme: ThemeData(
    // Define the default brightness and colors.
    primaryColor: Colors.white,
    shadowColor: Colors.transparent,
    backgroundColor: Colors.white70,
    iconTheme: const IconThemeData(color: Colors.black87),

    // Define the default font family.
    fontFamily: 'Georgia',
),

// Define the border of the image if needed.
imageBorder: Border.all(color: Colors.black87, width: 2.0),

// Define the border of the icon if needed.
editIconBorder: Border.all(color: Colors.black87, width: 2.0),
),

Additional information

This package has been written solely in Dart Language yet it has the wechat_assets_picker as a dependency. Therefore, EditableImage currently supports only Android, iOS, and macOS platforms. In the future, other platform supports may be added.
