Взаимодействие со смарт-контрактом Ink

Question

Сначала мы поместим код смарт-контракта в блокчейн с помощью

const result = await api.tx.contracts.putCode(bytes).signAndSend(pair)

тогда мы создадим контракт с

const instantiate = await api.tx.contracts.instantiate(0, 500000, result, abi.constructors[0]).signAndSend(pair)

Как мы устанавливаем значение init, вызываем get и вызываем метод flip следующего контракта с polkadot js?

mod flipper {
    use ink_core::storage;

    /// Defines the storage of your contract.
    /// Add new fields to the below struct in order
    /// to add new static storage fields to your contract.
    #[ink(storage)]
    struct Flipper {
        /// Stores a single `bool` value on the storage.
        value: storage::Value<bool>,
    }

    impl Flipper {
        /// Constructor that initializes the `bool` value to the given `init_value`.
        #[ink(constructor)]
        fn new(&mut self, init_value: bool) {
            self.value.set(init_value);
        }

        /// Constructor that initializes the `bool` value to `false`.
        ///
        /// Constructors can delegate to other constructors.
        #[ink(constructor)]
        fn default(&mut self) {
            self.new(false)
        }

        /// A message that can be called on instantiated contracts.
        /// This one flips the value of the stored `bool` from `true`
        /// to `false` and vice versa.
        #[ink(message)]
        fn flip(&mut self) {
            *self.value = !self.get();
        }

        /// Simply returns the current value of our `bool`.
        #[ink(message)]
        fn get(&self) -> bool {
            *self.value
        }
    }
}
