Shamir's Secret Sharing is an algorithm in cryptography created by Adi Shamir. It is a form of secret sharing, where a secret is divided into parts, giving each participant its own unique part.

To reconstruct the original secret, a minimum number of parts is required. In the threshold scheme this number is less than the total number of parts. Otherwise all participants are needed to reconstruct the original secret.

Add your Flutter Launcher Icons configuration to your pubspec.yaml

dev_dependencies:
  flutter_launcher_icons: "^0.8.0"

flutter_icons:
  android: true
