ChartsConfig class

Optional configuration shared by all chart widgets.

Use ChartsConfig to set theme, visual effects, empty/error UI, and shadows in one place. When passed to a chart, config values override the chart's individual parameters when provided.

All parameters are optional. Omitted values fall back to the chart's own parameters or defaults.

Example

final config = ChartsConfig(
  theme: ChartTheme.light(),
  useGlassmorphism: true,
  emptyMessage: 'No data yet',
  errorMessage: 'Something went wrong',
);

LineChartWidget(
  dataSets: dataSets,
  config: config,
)
