This question already has an answer here:
How do I initialize a composed struct in Go? (1 answer)
Closed 8 months ago.
I have two packages where Package B imports Package A, like this:
Package A
package Atype Car struct {Color stringMake stringModel string
}
Package B
package Btype car struct {*A.Car
}func NewCar() car {return &car{Color: "red",Make: "toyota",Model: "prius"}
}
However, this gives me the error: cannot use promoted field Car.Color in struct literal of type car inside NewCar function, how do I fix this? Everything I have read online just makes me more confused.

You need:
func NewCar() *car {return &car{ &A.Car{Color: "red",Make: "toyota",Model: "prius",}}
}
See https://github.com/golang/go/issues/9859 for:
