Dumping Sequence topic

Dumps any object in Dart that implements Iterable.

Flow Sequences

Flow sequences start with [ and terminate with ]. All entries are always dumped on a new line. The default scalar style for flow sequences is ScalarStyle.doubleQuoted.

dumpSequence(
  ['hello', 24, true, 24.0],
  collectionNodeStyle: NodeStyle.flow,
);

# Output in yaml
[
 "hello",
 "24",
 "true",
 "24.0"
]

Block Sequences

Block sequences have no explicit starting or terminating indicators. However, entries always have a leading - . The default scalar style for block sequences is ScalarStyle.literal.

dumpSequence(
  ['hello', 24, true, 24.0],
  collectionNodeStyle: NodeStyle.block,
);

# Output in yaml
- |-
  hello
- |-
  24
- |-
  true
- |-
  24.0

You can still override the ScalarStyle by providing a preferredScalarStyle.

dumpSequence(
  ['hello', 24, true, 24.0],
  collectionNodeStyle: NodeStyle.block,
  preferredScalarStyle: ScalarStyle.plain,
);

# Output in yaml
- hello
- 24
- true
- 24.0
