Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> Mengimplementasikan ReceiptScreen dengan pola provider untuk manajemen state yang lebih baik. Memisahkan logika bisnis ke service terpisah dan membuat widget komponen yang reusable untuk struk. Menambahkan fitur konfigurasi informasi toko dan teks kustom (disclaimer, thank you note, pantun).master
