lex library

AWS Lex (V1).

Classes

AppConstant<T>
A value the Stack hands to application code as a static const in the generated AppExports file — known when synth runs, so the app compiles against it.
AppExports
Where synth writes the Dart file application code imports: the Stack's constants, as the static const members of <name>Constants, and a typed reader of its Terraform outputs, <name>Outputs.
AttributeRef<T>
Public for sealed pattern matching, but constructor is private — only TfRef.attribute() may construct instances.
AwsLexBot
Factory wrapper for aws_lex_bot.
AwsLexBotAlias
Factory wrapper for aws_lex_bot_alias.
AwsLexIntent
Factory wrapper for aws_lex_intent.
AwsLexSlotType
Factory wrapper for aws_lex_slot_type.
DartDefineOutput
An output whose value is the client build's --dart-define file, registered with Stack.addDartDefineOutput.
Data
Base of every user-instantiable Terraform data block.
DataAwsLexBot
Factory wrapper for aws_lex_bot.
DataAwsLexBotAlias
Factory wrapper for aws_lex_bot_alias.
DataAwsLexIntent
Factory wrapper for aws_lex_intent.
DataAwsLexSlotType
Factory wrapper for aws_lex_slot_type.
DataRef<T>
Public for sealed pattern matching, but constructor is private — only TfRef.data() may construct instances.
EnvironmentConstant
The AppConstant.fromEnvironment choice.
GcsBackend
terraform { backend "gcs" { ... } } configuration.
IgnoreAllChanges
IgnoreChanges.all.
IgnoreAttributes
IgnoreChanges.of.
IgnoreChanges
What ignore_changes covers: every attribute, or the listed ones.
InvalidDartDefineOutput
An output of Stack.addDartDefineOutput that cannot carry what it names: an output that is not registered, is sensitive or has no environment value, two outputs read from one variable, or no output at all.
InvalidLifecycle
A lifecycle block Terraform rejects: a data source (or one of its attributes) in replaceTriggeredBy, all inside IgnoreChanges.of, or a condition with an empty error message.
InvalidMoveTarget
A moved block whose to names no resource of the Stack.
InvalidTimeout
A negative timeouts duration.
LexBotAbortStatement
Typed helper for the abort_statement block of aws_lex_bot (derived from provider schema).
LexBotAliasConversationLogs
Typed helper for the conversation_logs block of aws_lex_bot_alias (derived from provider schema).
LexBotAliasLogSettings
Typed helper for the conversation_logs.log_settings block of aws_lex_bot_alias (derived from provider schema).
LexBotClarificationPrompt
Typed helper for the clarification_prompt block of aws_lex_bot (derived from provider schema).
LexBotIntent
Typed helper for the intent block of aws_lex_bot (derived from provider schema).
LexBotMessage
Typed helper for the abort_statement.message block of aws_lex_bot (derived from provider schema). Shared by every block of this shape in the resource.
LexIntentClosing
At most one of conclusion_statement, follow_up_prompt on aws_lex_intent: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
LexIntentClosingConclusionStatement
The LexIntentClosing.conclusionStatement choice: sets conclusion_statement.
LexIntentClosingFollowUpPrompt
The LexIntentClosing.followUpPrompt choice: sets follow_up_prompt.
LexIntentCodeHook
Typed helper for the fulfillment_activity.code_hook block of aws_lex_intent (derived from provider schema).
LexIntentConclusionStatement
Typed helper for the conclusion_statement block of aws_lex_intent (derived from provider schema).
LexIntentConfirmationPrompt
Typed helper for the confirmation_prompt block of aws_lex_intent (derived from provider schema).
LexIntentDialogCodeHook
Typed helper for the dialog_code_hook block of aws_lex_intent (derived from provider schema).
LexIntentFollowUpPrompt
Typed helper for the follow_up_prompt block of aws_lex_intent (derived from provider schema).
LexIntentFulfillmentActivity
Typed helper for the fulfillment_activity block of aws_lex_intent (derived from provider schema).
LexIntentMessage
Typed helper for the conclusion_statement.message block of aws_lex_intent (derived from provider schema). Shared by every block of this shape in the resource.
LexIntentPrompt
Typed helper for the follow_up_prompt.prompt block of aws_lex_intent (derived from provider schema).
LexIntentRejectionStatement
Typed helper for the rejection_statement block of aws_lex_intent (derived from provider schema). Shared by every block of this shape in the resource.
LexIntentSlot
Typed helper for the slot block of aws_lex_intent (derived from provider schema).
LexIntentValueElicitationPrompt
Typed helper for the slot.value_elicitation_prompt block of aws_lex_intent (derived from provider schema).
LexSlotTypeEnumerationValue
Typed helper for the enumeration_value block of aws_lex_slot_type (derived from provider schema).
LifecycleCondition
A precondition or postcondition block: Terraform fails the plan (LifecycleCondition.pre) or the apply (LifecycleCondition.post) with errorMessage when condition is false.
LifecycleOptions
lifecycle { ... } block on a resource.
LocalBackend
terraform { backend "local" { ... } } configuration.
MissingProvider
A block needs a provider configuration the Stack does not register: the provider its type implies (google for google_pubsub_topic), the one its provider meta-argument names, or one a module call passes on.
ModuleCall
A module "<localName>" { ... } call as a Dart value.
NoProviders
The Stack registers no provider, but declares resources or data sources.
ProviderConflict
Two provider registrations Terraform rejects together: two defaults of one name, a repeated alias, an alias that is not an identifier, or configurations of one name with different source / version constraints.
RefConstant<T>
The AppConstant.ref choice.
ReplaceTrigger
What lifecycle.replaceTriggeredBy lists: a resource of the Stack or an attribute getter of one. Resource and TfRef implement it; synth reports a data source or a data-source attribute as an InvalidLifecycle.
Resource
Base of every user-instantiable Terraform resource.
ResourceRef
Public for sealed pattern matching, but constructor is private — only TfRef.resource() may construct instances.
S3Backend
terraform { backend "s3" { ... } } configuration.
Sensitive<T>
What an argument Terraform marks sensitive takes: a variable, an expression or an attribute getter — a value Terraform resolves, never a Dart literal that would be written into main.tf.json.
SensitiveLiteral
A sensitive field is set to a literal, which would write the secret in plain text into main.tf.json.
Stack
User-extended IaC composition root.
StackBackend
Lightweight backend hook. Core ships GcsBackend, S3Backend, and LocalBackend; anything else implements this interface in the caller. The Stack only stores the value and exposes a discriminator for synth's terraform { backend ... } emitter.
StackProvider
Coordination interface between Stack (in this package) and concrete providers (e.g. GoogleProvider in terradart_google). Concrete providers implement every getter using their baked-in constants from Stage 2 codegen.
SynthIssue
One reason a Stack cannot be synthesized.
SynthResult
Bundle returned by StackSynth.synth.
TfAddressed
Anything that exposes a Terraform address, e.g. google_pubsub_topic.orders.
TfArg<T>
A Terraform argument: a Dart-side literal, a reference to another block's attribute (TfRef), a variable or a raw expression.
TfArgExpression<T>
A raw Terraform expression — the tf.json template string, verbatim.
TfArgLiteral<T>
TfArgVariable<T>
TfCollectionType
list(...), set(...) or map(...).
TfMoved
One moved { from = ... to = ... } block: the state object at from now belongs to the resource at to, so a rename does not become a destroy-and-create.
TfObjectType
object({ ... }).
TfOptionalType
optional(<type>[, <default>]).
TfOutput<T>
An output "<name>" { value = ... } block, registered with Stack.addOutput.
TfPrimitiveType
string, number, bool or any.
TfRef<T>
A Terraform-side reference: an attribute of a resource (AttributeRef) or a data source (DataRef), or a whole resource (ResourceRef).
TfTimeouts
timeouts { ... } on a resource or data source: how long Terraform waits for each operation before giving up.
TfTupleType
tuple([...]).
TfType
A Terraform type constraint: string, list(number), object({ name = string }).
TfVariable
One variable "<name>" { ... } declaration.
UndeclaredVariable
A TfArg.variable or var.<name> in an expression names a variable the Stack does not declare.
UnregisteredReference
A block references another block that was never registered on the Stack: built, but not passed to add(...) / addModule(...).
UnresolvableConstant
An AppConstant.ref whose value is not known at synth: the attribute is not set to a literal, is sensitive, does not match the constant's type, or belongs to a block that is not registered.
ValueConstant<T>
The AppConstant.value choice.

Enums

ResourceKind
Whether a Stack entry is a resource block or a data block in Terraform JSON.

Extension Types

LexBotLocale
Lex Bot enum for locale.
LexBotProcessBehavior
Lex Bot Process enum for process_behavior.
LexIntentSlotConstraint
slot_constraint — derived from the provider schema description.
LexIntentType
type — derived from the provider schema description.
LexSlotTypeValueSelectionStrategy
Lex Slot Type Value Selection enum for value_selection_strategy.
OutputEnvironment
The environment Stack.outputEnvironment returns: each variable and its value, in registration order.
RefTo
A reference to a resource of type R, for an argument that names another resource (network, vpc_id, role_arn, ...).

Extensions

RefToList on TfArg<List<RefTo<R>>>
A list-valued reference argument (security_group_ids, subnet_ids): a literal list of RefTos, or one value that is the whole list (TfArg.variable('subnet_ids'), TfArg.expression(...)).
TerraformDurationExt on Duration
Converts a Dart Duration into a Terraform duration string ("604800s").

Exceptions / Errors

DuplicateModuleError
A ModuleCall registered twice under one name.
DuplicateResourceError
Thrown by Stack.add when an entry with the same (kind, terraformType, localName) triple is registered twice.
SynthException
Thrown by Stack.synth() and Stack.writeTo() when the Stack has one or more SynthIssues. Nothing is written.
