safeParseInt

Any argument value will be attempted to be parsed as a Number type without returning an error. If parsing fails, it is replaced by the number set in fallback. The default value for fallback is 0. You can specify radix (default is decimal: 10) in the third argument.

Parameters

Name	Type	Required	Default
value	any	●	–
fallbacknamed	number	–	0
radixnamed	number	–	10

named parameters are passed as named parameters in Dart and keyword arguments in Python.

Returns

number

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

Python

result1 = safeParseInt('00010')
result2 = safeParseInt('10.1234')
result3 = safeParseInt(None, -1)

print(result1)  # Returns 10
print(result2)  # Returns 10
print(result3)  # Returns -1
