readLine abstract method

FutureOr<String?> readLine({
  1. Encoding encoding = utf8,
})

Removes and returns characters up to but not including the next line break. A line break is either "\n" or "\r\n"; these characters are not included in the result.

On the end of the stream this method returns null, If the source doesn't end with a line break then an implicit line break is assumed. Null is returned once the source is exhausted. Use this for human-generated data, where a trailing line break is optional.

Implementation

FutureOr<String?> readLine({Encoding encoding = utf8});
