Make 2 Method with One (same parameter) - unity3d

Question

I think this is beginner stuff, but I still need to find a way to solve this.
I want to make the bool logic reference of the bool logar. The invisiblearrow(), I applied in toggle button in world space Unity thus I want to pass the logar to logic bool.(same bool).
private void invisiblearrow(bool logar) {
if (logar == false) {
GameObject[] arrow = GameObject.FindGameObjectsWithTag("arrow");
foreach(GameObject ar in arrow) {
ar.GetComponent < Renderer > ().enabled = logar;
Debug.Log(logar);
}
}
if (logar == true) {
GameObject[] arrow = GameObject.FindGameObjectsWithTag("arrow");
foreach(GameObject ar in arrow) {
ar.GetComponent < Renderer > ().enabled = logar;
Debug.Log(logar);
}
}
}
public void arrow(float[, ] arrowdata, bool logic) {
for (int x = 0; x < arrowdata.GetLength(0); x++) {
for (int y = 0; y < arrowdata.GetLength(1); y++) {
if (grid[x, y] == 1) {
if (arrowdata[x, y] == 5) {
GameObject referenceArrow = Instantiate(Resources.Load("down")) as GameObject;
float posY = shipvalue.transform.position.y - 9f;
referenceArrow.transform.position = new Vector3(shipvalue.transform.position.x, posY);
referenceArrow.GetComponent < Renderer > ().enabled = logic;
}
if (arrowdata[x, y] == 4) {
GameObject referenceArrow = Instantiate(Resources.Load("top left")) as GameObject;
float posY = shipvalue.transform.position.y - 9f;
referenceArrow.transform.position = new Vector3(shipvalue.transform.position.x, posY);
referenceArrow.GetComponent < Renderer > ().enabled = logic;
}
if (arrowdata[x, y] == 3) {
GameObject referenceArrow = Instantiate(Resources.Load("top right")) as GameObject;
float posY = shipvalue.transform.position.y - 9f;
referenceArrow.transform.position = new Vector3(shipvalue.transform.position.x, posY);
referenceArrow.GetComponent < Renderer > ().enabled = logic;
}
}
}
}
}

You can't because both bools are local bool (at the level of the function only), but you can:
Declare a private bool outside the two function (global), and at the end of invisiblearrow(bool logar) function, assign logar bool value to the new private bool (the new bool = logar), then you can access the new private bool in arrow(float[,] arrowdata, bool logic) function.
