Attempts to parse without returning an error, even if the argument value is of the wrong type or in JSON format. If parsing fails, it will be replaced with the object set in fallback. The default value for fallback is an empty object.

Parameters

jsonString	any	●	–
fallbacknamed	object	–	{}

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

Returns

Examples

JavaScript

const result1 = safeJSONParse('{"a":1,"b":2}');
const result2 = safeJSONParse(null);

console.log(result1); // Returns { a: 1, b: 2 }
console.log(result2); // Returns {}

Dart

final result1 = safeJSONParse('{"a":1,"b":2}');
final result2 = safeJSONParse(null);

print(result1); // Returns { a: 1, b: 2 }
print(result2); // Returns {}

Python

result1 = safeJSONParse('{"a":1,"b":2}')
result2 = safeJSONParse(None)

print(result1)  # Returns { a: 1, b: 2 }
print(result2)  # Returns {}
