Penerapan ViewModel dan State in Compose

pada Unscramble App

Aplikasi Unscramble App adalah aplikasi permainan game yang akan menampilkan kata acak. Objective kita dalah untuk memecahkan kata nya itu supaya terutut dan setiap kata yang benar akan mendapatkan 10 poin.

Terdapat 2 tombol, submit dan skip. Submit berfungsi sebagai tombol untuk mengirimkan jawaban yang di tebak, lalu skip untuk melewati soal dan tidak akan mendapatkan point.

Jika jawaban yang dikumpulkan tidak benar/salah, maka tidak akan mendapatkan point.

Berikut adalah codingan dari aplikasi ini :
