Data type conversion in Dart or Flutter

In Dart and Flutter, you can perform data type conversions using various methods and constructors provided by the language. Here are some commonly used data type conversions:

String stringValue = '123';
int intValue = int.parse(stringValue);

String to double:

String stringValue = '3.14';

int to String:

int intValue = 42;
String stringValue = intValue.toString();
Code language: JavaScript (javascript)

double to String:

double doubleValue = 3.14;
String stringValue = doubleValue.toString();
Code language: JavaScript (javascript)

String to boolean:

String stringValue = 'true';
bool boolValue = stringValue.toLowerCase() == 'true';
Code language: JavaScript (javascript)

boolean to String:

bool boolValue = true;
String stringValue = boolValue.toString();
Code language: JavaScript (javascript)
