Explain what is meant by implicit type conversion in the Dart language

Implicit type conversion in Dart is the automatic conversion of a value from one type to another by the compiler or runtime environment without explicit indication from the programmer.

In Dart, this occurs, for example, during arithmetic operations between int and double, where int is automatically converted to double for correct calculation.

Example:

int a = 5;
double b = 3.2;
double c = a + b; // a is implicitly converted to double
print(c); // 8.2

However, Dart is a strictly typed language, and implicit conversions are limited. In most cases, explicit conversion is required to avoid errors.
