Very easy! first of all, let's install like normal Go packages

Create a new variable

all you need to have is a basic variable and a nullable variable created with nullable.NewUint(yourBasicVar).

import (
    "fmt"
    "gorm.io/gorm"
    "github.com/Valdenirmezadri/nullable"
)

func main() {
    // Create new
    var theNumber uint64 = 70
    nullableNumber := nullable.NewUint(theNumber)
    fmt.Println(nullableNumber.Get()) // Output: 70

    // Change to another number
    var anotherNumber uint64 = 3306
    nullableNumber.Set(anotherNumber)
    fmt.Println(nullableNumber.Get()) // Output: 3306

    // Change to nil
    nullableNumber.Set(nil)
    fmt.Println(nullableNumber.Get()) // Output: 0
}
