Making Animated GIFs Of Flutter Apps

Animated GIFs are useful for documenting animations. Here's how to make them:

Capturing video of an Android device

• This feature is available on KitKat and later.

• Make sure to launch the app using flutter run --release for faster performance.

• Start recording video by running this command on the command line:

  adb shell screenrecord /sdcard/recording.mp4

• Interact with the app. When you are done you can terminate the recording with CTRL+c.

• Pull the recording off the device and onto your local hard drive:

  adb pull /sdcard/recording.mp4 ~/Downloads/

Capturing video of the iOS simulator

• Move the iOS simulator above your other applications
• Launch the "QuickTime Player" app
• Select “New Screen Recording” from the File menu
• Draw a box around the Simulator and click "Start Recording"
• When you're finished, click on Stop Recording on the Menu Bar.
• If needed, trim your recording using "Trim" from the "Edit" menu.
• Save the recording

Converting the recording to GIF

• Go to http://ezgif.com/video-to-gif and upload the video.
• If further trimming is needed, select the start and end times for your GIF.
• Select an appropriately small size for the GIF (recommended: 320xAUTO).
• Select a high framerate for the GIF (the max is 20) for smoothest animation
• Convert to GIF and download the GIF file
