level property

num get level

Gets or sets the number of single-parent ancestors this node has.

This could also be interpreted as which layer this node is in. A root node will have a value of zero.

This informational property is computed in TreeLayout#doLayout when building the tree structures. You should probably not be setting this property.

Implementation

_i2.num get level => _i4.getProperty(
      this,
      'level',
    );

set level (num value)

Implementation

set level(_i2.num value) {
  _i4.setProperty(
    this,
    'level',
    value,
  );
}
