checking if grounded without using oncollision enter/exit?

so I have a script that rotates a cube (by 90 degrees when a direction is pressed) currently im using the oncollision enter to detect walls and when I try to use it to also check if grounded then it will just completely stop everything when i leave one collision and enter another, or it won't fully check when im in mid air and will allow me to move when i don't want to be able to. Any and all help is greatly appreciated.

I think the most simple and common way to do ground checks is with casting a ray. So just cast a ray into the direction you want to check or try Overlap functions.
Example:
if(Physics.OverlapCircle(point, radius, layerMask)) {
//do stuff
}
So just cast a ray in all direction you want to check or add a overlap function to each side of the cube.

Why does my script make my "dash" have a seemingly random duration and how can I fix it?

I am new to coding. I've been trying to Frankenstein basic tutorials into something of my own and it seems ive finally hit a wall. I'm really not sure what is causing this and would like some help to weed out the problem.
at the moment when I press the dash button (left shift) my character dashes in the direction he is facing but for a random duration. I would like it to be consistent and working properly.
Thanks in advance!
PS: Sorry for the long script, it contains everything to do with player movment.

Random duration is because of the use of Rigidbody2D.
See in Unity Rigidbody2D is responsible for each and every single physical interaction. It mean forces from player like player movement and forces from your environment like friction and collision.
Here what is happening is that when your player is dashing there is also player movement force, which is also applied on your player's Rigidbody2d. And friction of ground on which your player is running/dashing on.
I've added a comment on parts that I've changed.
Updated part of your script:
private bool isDashing;
.
.
.
void Update()
{
//Added: putting a Condition to check if you player is not dashing, if it is then
//player won't be able to do anything, As I've scene and done in many games. if you
//don't want this remove it and see what happens, this is not tested so sorry if there
//is something that is not working as intended.
//dashing condition check

// Moving

How to do player movement calculations on c# console from unity movement

Question: How do i go about doing a equation on a c# console for where the player should be based on player input from unity.
To explain farther, the client is ran in unity and the server is a c# console application. When the player presses a movement key ex. (w, witch moves the player forward based on local position, as to always make the player move forward) it sends to the server that player pressed w, and then the sever responds and tells the client that it pressed w, changing the player w is pressed bool to true. Then the character moves.
Essentially I am trying to figure out how to make a equation that will do what unity does, but without a transform, or even how the transform works so that i can apply it to the server side.
Here is the client side code:

Edit:
so i have figured out a equation that i am using to try and mimic player movement, as of right now it only work between 0 and 90 degrees, just tell i get it exact. the equation comes out really close, but is just a tiny bit off. Any suggestions? Also, this is running on client side, no server influence, so that I can get the math to an exact. The math comes out about 1 unit per second slower then the players current position. Basically after pressing w for 1 second with speed = 20 the math comes out to 19 and actual position is 20.
here is code
if (CharContr.velocity != Vector3.zero)//checks if the player is moving
{
if (rotation < 90f && rotation > 0f) // makes sure the rotation is 0-90
{
percent = (100 / (90 / rotation)) / 100; // gets the percent
x = x + (percent * speed * Time.deltaTime); //adds to current position multiplied by speed and delta time
invertPercent = 1 - percent; //gets the percent for z
z = z + (invertPercent * speed * Time.deltaTime); // adds and stuff again
}

This is really complicated than you thought if you want to implement it yourself instead of using Unity's built-in NetworkTransform. Read this "Client-Side Prediction and Server Reconciliation" article. There are many parts of that article but it shows you what's going on and how this is done.
Although, Unity simplified a part of this if you are using Rigidbody by providing a new function (Physics.Simulate). You simulate all the Rigidbody on the server with the Physics.Simulate function, serialize the transform of each one and send to all the clients.
On the clients, receive the data, de-serialize them then lerp from the current transform to the received ones. You can find an example of how to use Physics.Simulate to determine the position of a Rigidbody in x second here.

Sending keycode to server and syncronize position based on bool is not best practice.
The good practice would be, sending 3 float value of x, y, and z position to the server, then broadcast it to other player.
so other player has the exact position without approximation
Sorry if i answer in wrong place, because i don't have enough rep to make comment.

so i did some searching and have come up with a solution, this is only for if the player is moving forward and the player direction is between 0 and 90. basically i have to use transform.translate instead of using a character controller. the reason i am doing this is so that when the player presses w it will send it to the server and the server can run this at the same time, then use the info to be able to tell were players should be.
if (rotation < 90f && rotation > 0f)
{
moveDirection = new Vector3(0, 0, 0);
percent = (100 / (90 / rotation)) / 100;
invertPercent = 1 - percent;
x = percent * speed;
z = invertPercent * speed;
transform.Translate(x * Time.deltaTime, 0, z * Time.deltaTime, Space.World);
newposition = newposition + new Vector3(x * Time.deltaTime, 0, z * Time.deltaTime);
}
