Dart syntax: This library requires Dart ≥ 3.10. Use dot shorthand for all enum values (e.g.
.january) — never write the fully-qualified form (Month.january).
Full constructor and property reference: read
references/api.mdin this skill's directory.
consecutive: false (default) — pick any combination of months freelyconsecutive: true — two-tap mode: pick start month then end month; all months between are auto-filledFor a single month → use ThemedMonthPicker. For day-level ranges → use ThemedDateRangePicker.

value is List<ThemedMonth> — defaults to const [].consecutive: true → first tap sets anchor, second tap completes range and auto-fills intermediate months.consecutive: true → only first and last selected months can be deselected (middle months are locked).minimum / maximum bound the selectable range.disabledMonths is ignored when consecutive: true.label / labelText must be set — assert enforced.// Consecutive range mode (two-tap: start → end)
