Flutter AI Photo Editor — Build a Canva App from Scrath

Set up the macOS Flutter environment by downloading the flutter SDK, organizing it in a development folder, updating your path via zshrc or zsh env, and verifying Flutter version.

Install Android Studio to build Flutter apps for the offline AI image editing app in Flutter with segmentation, and enable Flutter projects by installing the plugin.

Install and set up Xcode on Mac to run Flutter apps on iOS and Mac devices, including App Store download, Xcode preferences, and selecting command line tools.

Create a new Flutter project in Android Studio, choose Kotlin for Android and iOS, and install the default counter app on iOS simulator and Android emulator.

Create and launch an Android emulator, selecting Pixel 7 with Android 14, download the image, and install the application inside the emulator.

Download the flutter sdk for windows, unzip it, place the flutter folder in the c drive, then add the bin path to your environment variables and run flutter doctor.

Install Android Studio, set up flutter by adding the dart and flutter plugins, and run flutter doctor to verify the setup and accept licenses.

Learn how to create an Android virtual device in Android Studio, download Android 14, configure orientation, and launch the emulator to test applications on a Pixel 7 Pro device.

Build a Flutter image picker app with a GUI, enabling gallery selection or camera capture and displaying the chosen image for use with machine learning models.

Add the image_picker library via pub.dev, update pubspec.yaml, and run pubget to enable image selection or capture; Android requires no extra setup, and configure iOS permissions in Info.plist.

Learn to implement the image picker library in flutter for choosing images from the gallery or camera, including creating and initializing the image picker object in initState.

Long-press the button to open the camera, capture images with the image picker using the camera source, and display the captured image on screen for testing on Android emulator.

Explore building a Flutter image picker app by integrating the library, configuring iOS permissions, and handling choose or capture actions to display the selected image from xFile.

Clone the starter Flutter image picker app, configure dependencies and iOS permissions, and test gallery and camera image selection in an emulator before passing images to the segmentation model.

Integrate Google ML Kit selfie segmentation in Flutter, install the pub.dev package, and configure Android min sdk 21 and sdk 35 to enable cross-platform, real-time background separation.

Load and initialize an on-device image segmentation model in Flutter, convert images to input image, and configure the selfie segmenter with single mode and raw size mask.

Learn how to pass an input image to a selfie segmentation model in Flutter, perform async inference, and obtain a segmentation mask to remove the background.

Transform segmentation results into a transparent Flutter image by iterating pixels, applying confidence scores to keep the person, and using the image library to build the output.

Apply a threshold of 0.5 to iterate each pixel, copy confident pixels into an output image, and set the rest transparent, creating a png for the Flutter user interface.

Test and validate image segmentation results by selecting photos from the gallery, confirming transparency around subjects, and saving transparent pngs to the gallery.

Set the output image to four channels to enable transparency when saving in Flutter, after background removal, by specifying the num channels parameter in the image library.

Explore the end-to-end flutter app workflow for offline ai image editing with segmentation, converting images to model input, applying the mask, and generating a transparent output.

Interpret the model's 256x256 segmentation mask to compute per-pixel confidence on the original image. Map mask coordinates to pixels and copy or make transparent based on that confidence.

Increase the image size to 450 and hot reload to view segmentation clearly, then adjust the threshold from 0.3 to 0.8 to balance transparency.

Add a save button when the segmented image is ready, and save it to the device gallery as a transparent PNG using image_gallery_saver_plus and path_provider.

Save segmented images to the gallery in Flutter using a provided save function, path provider, and image gallery saver, writing PNG bytes to a temp file.

Learn to replace an image background in flutter by making it transparent. Apply a background from assets by declaring it in pubspec using image segmentation and the img library.

Display a horizontal list view of background options from assets, including a transparent png, and apply the chosen background to the image during segmentation.

Wraps list view images in a gesture detector, updates the selected background on tap, runs image segmentation, and applies the chosen background to the image.

Demonstrates enhancing background selection in a Flutter list by highlighting the selected item with a deep purple border and rounded corners, using container, box decoration, and clip radius.

Optimize the Flutter UI by refining the app bar, centering the title, and enhancing the image display with a circular bordered container, shadows, and background color.

Display a placeholder image in flutter by replacing the gray box with an image icon, sized 200 and gray, then adjust height and add a bottom margin of 30.

Design and style the gallery and camera buttons in Flutter, using a bottom app bar with inkwell taps to pick images from gallery or capture with camera.

Designs a save and share button in Flutter UI, styling an elevated icon button with a download icon, white text, deep purple background, and rounded corners.

Enable users to share edited images in flutter using the share plus package. The lecture covers adding the dependency, saving a temp file, and sharing via apps like WhatsApp.

Demonstrates how to display a checkerboard transparency pattern in a Flutter list view by conditionally swapping between a transparent png and t2.png to indicate image transparency.

Learn to display a transparent background behind segmented images in Flutter by using a stack, showing a transparent asset conditionally, and managing button states based on mask data.

Create a left-to-right animated transparent background using an animation controller, a tween from 0 to 1, and a one-second duration, applied with an animated builder and align widthFactor.
