barData method

List<Map<String, dynamic>> barData({
  1. int bars = 10,
  2. double minValue = 10,
  3. double maxValue = 100,
  4. List<String>? categories,
})

Generates bar chart data.

Implementation

List<Map<String, dynamic>> barData({
  int bars = 10,
  double minValue = 10,
  double maxValue = 100,
  List<String>? categories,
}) {
  return List.generate(bars, (i) {
    return {
      'category': categories?[i] ?? 'Category ${i + 1}',
      'value': _random.uniform(minValue, maxValue),
    };
  });
}
