AWS Config.

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.
AwsConfigAggregateAuthorization
Factory wrapper for aws_config_aggregate_authorization.
AwsConfigConfigRule
Factory wrapper for aws_config_config_rule.
AwsConfigConfigurationAggregator
Factory wrapper for aws_config_configuration_aggregator.
AwsConfigConfigurationRecorder
Factory wrapper for aws_config_configuration_recorder.
AwsConfigConfigurationRecorderStatus
Factory wrapper for aws_config_configuration_recorder_status.
AwsConfigConformancePack
Factory wrapper for aws_config_conformance_pack.

ConfigAggregateAuthorizationAuthorizedAwsRegion
The ConfigAggregateAuthorizationRegion.authorizedAwsRegion choice: sets authorized_aws_region.
ConfigAggregateAuthorizationRegion
Exactly one of authorized_aws_region, region on aws_config_aggregate_authorization: the provider rejects none and more than one, so each variant sets one of them.
ConfigAggregateAuthorizationRegionChoice
The ConfigAggregateAuthorizationRegion.region choice: sets region.
ConfigConfigRuleCustomPolicyDetails
Typed helper for the source.custom_policy_details block of aws_config_config_rule (derived from provider schema).
ConfigConfigRuleEvaluationMode
Typed helper for the evaluation_mode block of aws_config_config_rule (derived from provider schema).
ConfigConfigRuleScope
Typed helper for the scope block of aws_config_config_rule (derived from provider schema).
ConfigConfigRuleSource
Typed helper for the source block of aws_config_config_rule (derived from provider schema).
ConfigConfigRuleSourceDetail
Typed helper for the source.source_detail block of aws_config_config_rule (derived from provider schema).
ConfigConfigurationAggregatorAccountAggregationSource
Typed helper for the account_aggregation_source block of aws_config_configuration_aggregator (derived from provider schema).
ConfigConfigurationAggregatorAccountAggregationSourceChoice
The ConfigConfigurationAggregatorAggregationSource.accountAggregationSource choice: sets account_aggregation_source.
ConfigConfigurationAggregatorAggregationSource
At most one of account_aggregation_source, organization_aggregation_source on aws_config_configuration_aggregator: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
ConfigConfigurationAggregatorOrganizationAggregationSource
Typed helper for the organization_aggregation_source block of aws_config_configuration_aggregator (derived from provider schema).
ConfigConfigurationAggregatorOrganizationAggregationSourceChoice
The ConfigConfigurationAggregatorAggregationSource.organizationAggregationSource choice: sets organization_aggregation_source.
ConfigConfigurationRecorderExclusionByResourceTypes
Typed helper for the recording_group.exclusion_by_resource_types block of aws_config_configuration_recorder (derived from provider schema).
ConfigConfigurationRecorderRecordingGroup
Typed helper for the recording_group block of aws_config_configuration_recorder (derived from provider schema).
ConfigConfigurationRecorderRecordingMode
Typed helper for the recording_mode block of aws_config_configuration_recorder (derived from provider schema).
ConfigConfigurationRecorderRecordingModeOverride
Typed helper for the recording_mode.recording_mode_override block of aws_config_configuration_recorder (derived from provider schema).
ConfigConfigurationRecorderRecordingStrategy
Typed helper for the recording_group.recording_strategy block of aws_config_configuration_recorder (derived from provider schema).
ConfigConformancePackInputParameter
Typed helper for the input_parameter block of aws_config_conformance_pack (derived from provider schema).

ConfigOrganizationConformancePackInputParameter
Typed helper for the input_parameter block of aws_config_organization_conformance_pack (derived from provider schema).
ConfigOrganizationConformancePackTemplate
At most one of template_body, template_s3_uri on aws_config_organization_conformance_pack: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
ConfigOrganizationConformancePackTemplateBody
The ConfigOrganizationConformancePackTemplate.templateBody choice: sets template_body.
ConfigOrganizationConformancePackTemplateS3Uri
The ConfigOrganizationConformancePackTemplate.templateS3Uri choice: sets template_s3_uri.
ConfigRemediationConfigurationExecutionControls
Typed helper for the execution_controls block of aws_config_remediation_configuration (derived from provider schema).
ConfigRemediationConfigurationParameter
Typed helper for the parameter block of aws_config_remediation_configuration (derived from provider schema).
ConfigRemediationConfigurationSsmControls
Typed helper for the execution_controls.ssm_controls block of aws_config_remediation_configuration (derived from provider schema).
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.
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.
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.

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").

Constants

terradartManifestVariable → const String
The environment variable the terradart command sets to the file runStack and runEnvironments describe what they wrote in.

Functions

runEnvironments<E extends Enum>(List<String> args, List<E> environments, Stack build(E env), {String dir(E env)?, String? workspace(E env)?, List<String> backendConfig(E env)?, E? defaultEnv}) → Future<void>
The entry point of a project with one Stack per environment. The environments are the members of an enum of the project's own — any names, each carrying its values — so the Stack takes a typed env and derives everything per environment from it, its backend included:
runStack(List<String> args, Stack build(), {String out = 'tf-out'}) → Future<void>
The entry point of a project with one Stack: writes it to out.

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.
