export method

String export({ List<num> range = const [0, 1], int steps = 100, int precision = 20, String label = '# x y', String delimiter = ' ', })

Returns a String containing a function table. Usage demonstrated below.

• range: A list containing the start and end points of the function argument. If range contains more than 2 entries these will be interpreted as the function arguments.
• steps: Number of table entries. Note: This parameter is ignored if range contains more than 2 entries. In that case steps == range.length.
• label: The first line of the output String.
• precision: The precision used to convert numbers to strings.

Usage:

import dart:math;
final table = sin.export(
  label: 'x     sin(x)',
  range: [0, 2*pi],
  steps: 5,
  precision: 4,
);
print(table);

A sample output is listed below:

x     sin(x)
0.0000 0.0000
0.39270 0.38268
0.78540 0.70711
1.1781 0.92388
1.5708 1.0000

Implementation

String export({
  List<num> range = const [0, 1],
  int steps = 100,
  int precision = 20,
  String label = '#     x     y',
  String delimiter = ' ',
}) {
  final table = this.table(range: range, steps: steps);
  return [
    table.keys.toList(),
    table.values.toList(),
  ].export(
      label: label, precision: precision, delimiter: delimiter, flip: true);
}
