I am new to flutter and I just want to display a list of alphabets in a for loop. I just want to know how can I convert the integer to ascii character. I searched for this and I found **dart:convert** library, but I don't know how to use it.

I want something like - 

```
for(int i=65; i<=90; i++){
print(ascii(i));    //ascii is not any method, its just to understand my question
}

```

It should print the letters from 'A' to 'Z'.
