type ‘int’ is not a subtype of type ‘string’ in Flutter

The error message you mentioned, “type ‘int’ is not a subtype of type ‘string’ in Flutter,” typically occurs when you try to assign an integer value to a variable or property that expects a string value.

To resolve this issue, you need to ensure that you are assigning a string value instead of an integer value where it is expected. Here are a few common scenarios where this error may occur and their potential solutions:

Assigning an integer to a string variable:

int myInt = 42;
String myString = myInt; // This will produce the error

To fix this, convert the integer to a string explicitly using the toString() method:

String myString = myInt.toString();

Passing an integer to a method that expects a string argument:

void printString(String text) {
  print(text);
}

int myInt = 42;
printString(myInt); // This will produce the error

To resolve this, again, convert the integer to a string before passing it to the method:

printString(myInt.toString());
