How to create custom image editing experiences in FlutterFlow?

Pre-requisites:

• Basic knowledge of Flutter
• FlutterFlow account
• Image editing API key (like imgly)

Step 1: Set Up Your FlutterFlow Project

Start by creating a new project in FlutterFlow. Provide a suitable project name and description.

Step 2: Design the Interface

The next step is to design the user interface for your image editing app. This comprises of:

• Buttons: Two buttons, one for uploading an image from the device and a second one for launching the image editing tools.
• Image Display: An image widget to display the selected or uploaded image.

Step 3: Set Up Firebase Authentication

Image processing generally requires user authentication. In the left-hand navigation bar of the FlutterFlow UI, go to the "Firebase" option. Here, you can configure your Firebase authentication by entering your Firebase credentials.

Step 4: Import Libraries

In your FlutterFlow, it's significant to import libraries that will facilitate using image editing capacities. One of them is the image_picker library.

Add the dependency in your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter

  image_picker: ^0.8.0+3

Step 5: Add the Upload Image Functionality

Now, it's time to add functionality to the 'Upload Image' button. You need to add an onPressed event and associate it with a predefined flutterflow action called pickImage which can pick an image from the device's gallery.

In the "Actions" tab, select the "Pick Image" action and set the "Max Width," "Max Height," and "Image Quality" as per your requirements.


Step 6: Display the Uploaded Image

In the image widget that you have created for displaying the uploaded image, change the source to the picked image from the ‘pickImage’ action.

Step 7: Add Image Editing Functionality

Next, add functionality to the 'Edit Image' button. You would typically have to use image editing APIs like imgly. You would need to create an account on the imgly website, get the invitational access, and retrieve your personal API keys.

To be able to use this in your app, add the dependency in your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter

  imgly_sdk: ^2.1.2

In the 'Actions' tab for the 'Edit Image' button, bind an 'onClick' event handler that will call the imgly SDK methods for image editing capabilities.

Step 8: Testing the App

Now, conduct a test of your application. Click the 'Run' button in the FlutterFlow interface to launch the application in the simulator or on your device.

We have successfully created a custom image editing experience in FlutterFlow. You can add more capabilities and features as per your requirements, like adding more image editing tools, filters, and even integrating it with cloud storage.
