Overview

dynamic ve var arasındaki fark

dynamic

Tanımlanan değişkenin tipi daha sonra kod içerisinde değişebilir. Örneğin int olarak tanımlanan bir a değişkenine daha sonra string bir değer ataması yapılabilir. Ataması yapılan değerle ilgili oluşabilecek hatalar runtime anında tespit edilebilir.

var

Tanımlanan değişkenin tipi daha sonradan değiştirilemez ve static checker ile hata olup olmadığı kod derlenmeden tespit edilir. Örneğin int olarak ataması yapılan b değişkenine daha sonradan string bir değer ataması yapılamaz. Kod yazım aşamasında hata verecektir.

Nasıl çalıştırılır ?

Indirdiğiniz projeyi klasöre çıkardıktan sonra terminalde projenin bulunduğu dizine giderek

dart run

komutunu çalıştırmanız yeterlidir.
