1. initialValue dan controller akan menghasilkan error jika ada di TextFormField yang sama

2. ketika mentimpan menggunakan onSaved TextFormField, jangan lupa menggunakan validator dan mengecek validasi dari TextFOrmFIedl dengan Syntax "formKey.currentstate.validated" dan janga "formKey.currentState.saved" di Buttom

3. Ketika ingin memisahkan widget di kelas / file yang berbeda. Pastikan pada variable VoidCallback tidak perlu menggunakan lambda. contoh: onPressed: callback jangan onPressed: ()=> callback

4. Refresh indicator hanya bisa melakukan refresh di ListView
