Installation

Add the following line to your pubspec.yaml file:

dependencies:
  ui_to_image: <latest_version>

IMPORTANT Note for iOS

If you are starting a new fresh app, you need to create the Flutter App with flutter create -i swift (see flutter/flutter#13422 (comment)), otherwise, you will get this message:

=== BUILD TARGET flutter_inappbrowser OF PROJECT Pods WITH CONFIGURATION Debug ===
The "Swift Language Version" (SWIFT_VERSION) build setting must be set to a supported value for targets which use Swift. Supported values are: 3.0, 4.0, 4.2. This setting can be set in the build settings editor.

If you still have this problem, try to edit iOS Podfile like this (see #15):

target 'Runner' do
  use_frameworks!  # required by simple_permission
  ...
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '4.0'  # required by simple_permission
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

Instead, if you have already a non-swift project, you can check this issue to solve the problem: Friction adding swift plugin to objective-c project.

Usage

Import the package

First, import the ui_to_image package in your Dart file:

import 'package:ui_to_image/ui_to_image.dart';

Create a UiToImage instance

Create an instance of UiToImage by providing your custom UI design widget, along with other optional parameters:

final UiToImage imageGenerator = UiToImage(
  customDesign: YourCustomWidget(), // Your custom UI design widget
  customText: "Custom text to highlight features",
  generatedImageName: 'custom_image.png',
  mimeType: 'image/png',
  shareTitle: 'Share via',
);

Replace YourCustomWidget() with the actual widget that represents your custom UI design.

Generate and share images

To generate an image from your custom UI design and share it, use the generateImage() method. If the image is generated successfully, you can then call the shareImage() method to share it:

// Generate and display the image
await imageGenerator.generateImage().then((success) {
  if (success) {
    // Image generated successfully
    imageGenerator.shareImage(); // Share the generated image
  } else {
    // Error generating image
  }
});

Load a previously generated image

You can use the loadLastImage() method to load a previously generated image:

File? imageFile = await imageGenerator.loadLastImage();
if (imageFile != null) {
  // Display the loaded image
}

This can be useful for scenarios where you want to display or process a previously generated image.

Note: Limitations on Widget Support

Please note that as of the current version, the package does not fully support ListView, GridView, or CustomScrollView widgets. It's recommended to avoid using these widgets directly within your custom design, as they may not be captured accurately in the generated image. However, we're actively working to improve widget support in upcoming versions.
