# JsonEncoder.withIndent constructor Null safety

const JsonEncoder.withIndent(

1. String? indent,
2. [Object? toEncodable(
   1. dynamic object
   )]

)

Creates a JSON encoder that creates multi-line JSON.

The encoding of elements of lists and maps are indented and put on separate lines. The `indent` string is prepended to these elements, once for each level of indentation.

If `indent` is `null`, the output is encoded as a single line.

The JSON encoder handles numbers, strings, booleans, null, lists and maps with string keys directly.

Any other object is attempted converted by `toEncodable` to an object that is of one of the convertible types.

If `toEncodable` is omitted, it defaults to calling `.toJson()` on the object.

## Implementation

    const JsonEncoder.withIndent(this.indent,
        [Object? toEncodable(dynamic object)?])
        : _toEncodable = toEncodable;
