Answer 1

When executing the SignUp function (at Material Button OnPressed), are the variables passed in the wrong order?

Answer 2

You're calling:
signUp(
emailController.text,
passwordController.text,
role,
vehicleNo.text,
name.text);
And signUp is defined as:
void signUp(String name, String email, String password, String role,
String vehicleNo) async {
So the order of the arguments is different between the two, leading you to call Firebase with the password value as the email address and the role value as the password.
To fix the problem, pass the arguments in the same order as signUp expects them.

Answer 3

It's almost always trailing whitespace, try:
postDetailsToFirestore(
email.trim(),
role,
name,
vehicleNo,
),
Alternatively you can also try to hardcode the right email address and check whether the problem is in logic or in UI.
