# tryParse method Null safety

int? tryParse (

1. String source,
2. {int? radix}

)
override

Parse `source` as a, possibly signed, integer literal and return its value.

Like parse except that this function returns `null` where a similar call to parse would throw a FormatException, and the `source` must still not be `null`.

## Implementation

    external static int? tryParse(String source, {int? radix});
