Properties

hashCode → int

The hash code for this object.

no setter, inherited

key → String

The key to store the answer in the data map.

final

onValidate → Future<String?> Function(String answer)?

Optional async callback for custom validation after the AI accepts the answer.

final

options → List<String>?

Optional fixed choices for this question. When non-empty, the chat shows chips or a searchable sheet (see optionsPresentation); the chosen string is sent to the model. The AI is instructed to accept only those values.

final

optionsChipMaxCount → int?

Overrides the automatic chip threshold (only used when optionsPresentation is null or QuestionOptionsPresentation.automatic).

final

optionsPresentation → QuestionOptionsPresentation?

How to show options. Null means QuestionOptionsPresentation.automatic: chips if the count is at most optionsChipMaxCount (default kDefaultOptionsChipMaxCount), otherwise a searchable bottom sheet.

final

optionsSheetTitle → String?

Title on the searchable sheet (e.g. Select country).

final

question → String

The question to ask the user.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

type → QuestionFieldType?

Optional hint for how to interpret answers (text vs numeric, etc.).

final

validationMessage → String?

Custom instructions for the AI on how to judge this answer (injected into the system prompt).

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Static Methods

normalizeOptionsList(List<String>? raw) → List<String>

Trim, drop empty entries, and dedupe by trimmed value (first occurrence wins).

useSearchableSheetForOptions({required List<String> normalized, QuestionOptionsPresentation? presentation, int? chipMaxCount}) → bool

Whether the UI should use the searchable sheet for this normalized option list.

Constants

kDefaultOptionsChipMaxCount → const int

Default max options shown as inline chips before using a searchable sheet.
