Latihan Aplikasi Arsip Barang di Fluter
Get 60 0FP0EXP Token to remove widget entirely!
Get 50000 0FP0EXP Token to remove my NFTS advertisements!
Permintaan
Dalam 3 hari, bikin aplikasi inventory sebagai berikut:
- pencatatan keluar masuk barang beserta harga per qty
- setiap barang diberi kategori untuk filter by kategori
- keluar masuk barang diberi keterangan timestamp (baik barang masuk maupun barang keluar) untuk keperluan filter by date
- setiap barang mempunyai harga jual dan harga beli
- buat form khusus untuk menambahkan dan mengurangi item
- untuk case mengurangi item diberikan pilihan (bukan inputan bebas) alasan barang keluar contoh: sold, expire, broken
- Tambahkan filter by case no 6
- Buat edit dan hapus barang
- Buat hasil rekap laporan per minggu (format bebas)
- Case authentication :
- cashier hanya dapat mengurangi barang
- admin gudang hanya dapat menambahkan dan mengurangi barang
- super admin dapat semua akses
Rancangan
Pencatatan keluar masuk barang beserta harga per qty
Membuat homepage kosong dan membuat halaman form untuk menambah barang dengan qty. Membuat form untuk memberi status jika barang dikeluarkan.
Setiap barang diberi kategori untuk filter by kategori
Halaman form tambah barang dimodifikasi untuk memberi kategori pada barang. Homepage ditambahkan fungsi filter.
keluar masuk barang diberi keterangan timestamp (baik barang masuk maupun barang keluar) untuk keperluan filter by date
Halaman form tambah barang dimodifikasi untuk memberi timestamp pada barang. Halaman form keluar barang dimodifikasi untuk menambah timestamp untuk barang keluar. Filter pada halaman homepage dimodifikasi agar dapat filter dengan tanggal.
setiap barang mempunyai harga jual dan harga beli
Form tambah ditambah input harga beli. Form keluar ditambah input harga jual.
buat form khusus untuk menambahkan dan mengurangi item
https://www.blackbox.ai/chhttps://www.blackbox.ai/chat/2MywfIAat/2MywfIA
untuk case mengurangi item diberikan pilihan (bukan inputan bebas) alasan barang keluar contoh: sold, expire, broken
Status form keluar ditambah input keterangan sold, expire, broken.
Tambahkan filter by case no 6
Filter halaman ditambah fungsi dapat memfilter alasan barangan keluar.
Buat edit dan hapus barang
Menambah form edit barang. Menambah form hapus barang.
Buat hasil rekap laporan per minggu (format bebas)
Hasil dapat export ke pdf, json, xml, dll.
Case authentication :
- cashier hanya dapat mengurangi barang
- admin gudang hanya dapat menambahkan dan mengurangi barang
- super admin dapat semua akses
