# Latin1Decoder constructor

const Latin1Decoder({bool allowInvalid: false })

Instantiates a new Latin1Decoder.

The optional `allowInvalid` argument defines how convert deals with invalid bytes.

If it is `true`, convert replaces invalid bytes with the Unicode Replacement character `U+FFFD` (�). Otherwise it throws a FormatException.

## Implementation

    const Latin1Decoder({bool allowInvalid = false})
        : super(allowInvalid, _latin1Mask);
