Enable character dash if a UI button is pressed - unity3d

Question

I'm currently trying to make a mobile game where my character can dash. All my character movements are manipulated through UI buttons. I have my "Move Left" button and my "Move Right button" with the directional functions. Here's my problem, how can I make a dash movement similar to that of Hollow Knight dash. I want my character to dash if I press a "dash" UI button. Here is my character movement code:
Rigidbody2D rb;
float playerspeed;
float movespeed;
float movespeedX;
private void Start()
{
rb = GetComponent <Rigidbody2D> ();
}
private void FixedUpdate()
{
Moveplayer(movespeed);
}
public void Moveplayer(float playerspeed)
{
myrb.velocity = new Vector2( movespeed, myrb.velocity.y);
if (playerspeed < 0 || playerspeed > 0 )
{
myanim.SetInteger ("State", 2);
}
}
public void Left()
{
movespeed = -movespeedX;
}
public void right()
{
movespeed = movespeedX;
}
public void StopMoving()
{
movespeed = 0;
}
public void Dash()
{
//execute dash when UI button is pressed
}
Thanks!

You need to create movement regardless of other forces, here is an example.
private bool enableMovement = false;
private float dashingTime = 1f;
private float dashingStrength = 2f;
private void FixedUpdate()
{
if (enableMovement)
Moveplayer(movespeed);
}
public Dash()
{
enableMovement = false;
StartCoroutine(Dashing());
}
private IEnumerator Dashing()
{
myrb.velocity = new Vector2(movespeed * dashingStrength, myrb.velocity.y);
yield return new WaitForSeconds(dashingTime);
enableMovement = true;
}
This is an easy simple way to achieve it.
