// Welcome to Cadence! This is one of the simplest programs you can deploy on Flow.
//
// The HelloWorld contract contains a single string field and a public getter function.
//
// Follow the "Hello, World!" tutorial to learn more: https://docs.onflow.org/cadence/tutorial/02-hello-world/
access(all) contract HelloWorld {
// Declare a public field of type String.
//
// All fields must be initialized in the init() function.
access(all) var greeting: String
// Public function that sets our friendly greeting!
// In your own applications you may want to tighten up this access control.
access(all) fun changeGreeting(newGreeting: String) {
self.greeting = newGreeting
}
// Public function that returns our friendly greeting!
access(all) fun hello(): String {
return self.greeting
}
// The init() function is required if the contract contains any fields.
init() {
self.greeting = "Hello, World!"
}
