Methods
-
appendAssistantTurn(String thinking, ({Map<String, dynamic> args, String tool}) action)
→ void
-
Append an assistant-role turn — the thinking text (empty when the
provider produced none) plus the validated tool call.
-
appendUserTurn(Observation obs, ObservationDiff diff, {Map<String, dynamic>? toolResult})
→ void
-
Append a user-role turn.
toolResult carries a previous action result
or a schema/validation-retry error map; null when this turn was a clean
observation.
-
estimatedTokens()
→ int
-
-
noSuchMethod(Invocation invocation)
→ dynamic
-
Invoked when a nonexistent method or property is accessed.
inherited
-
snapshot()
→ ConversationSnapshot
-
Immutable snapshot of the conversation state. The returned snapshot
reuses the same system-message string instance across calls — Dart
string canonicalisation makes the system prefix byte-identical for
KV-cache friendliness.
-
toString()
→ String
-
A string representation of this object.
inherited
-
trimIfOverBudget(int threshold)
→ void
-
Drop observation from the oldest non-trimmed UserTurn until
estimatedTokens is
<= threshold or no trimmable turns remain.
Trimmed turns keep their UserTurn.diff intact so the model still
sees the delta sequence; only the heavy observation body is
replaced with Observation.empty.
