Examples

JavaScript

const result1 = safeParseInt('00010');
const result2 = safeParseInt('10.1234');
const result3 = safeParseInt(null, -1);

console.log(result1); // Returns 10
console.log(result2); // Returns 10
console.log(result3); // Returns -1

Dart

final result1 = safeParseInt('00010');
final result2 = safeParseInt('10.1234');
final result3 = safeParseInt(null, -1);

print(result1); // Returns 10
print(result2); // Returns 10
print(result3); // Returns -1
