Pada pertemuan hari ini, diberikan tugas untuk membuat aplikasi Woof. Aplikasi Woof sendiri merupakan sebuah aplikasi yang menampilkan daftar anjing dengan menggunakan Desain Material untuk membuat tampilan dan pengalaman aplikasi yang menarik. Referensi latihan dapat dilihat pada link berikut ini Penerapan Tema Material dengan Jetpack Compose.
Setelah mendownload file yang ada pada referensi diatas, dilakukan beberapa perubahan kode.
