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.
AwsEmrBlockPublicAccessConfiguration: Factory wrapper for aws_emr_block_public_access_configuration.

Data: Base of every user-instantiable Terraform data block.
DataAwsEmrReleaseLabels: Factory wrapper for aws_emr_release_labels.
DataAwsEmrSupportedInstanceTypes: Factory wrapper for aws_emr_supported_instance_types.
DataEmrReleaseLabelsFilters: Typed helper for the filters block of aws_emr_release_labels (derived from provider schema).

EmrClusterBootstrapAction: Typed helper for the bootstrap_action block of aws_emr_cluster (derived from provider schema).
EmrClusterConfigurations: At most one of configurations, configurations_json on aws_emr_cluster: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
EmrClusterConfigurationsChoice: The EmrClusterConfigurations.configurations choice: sets configurations.
EmrClusterConfigurationsJson: The EmrClusterConfigurations.configurationsJson choice: sets configurations_json.
EmrClusterCoreInstanceFleet: Typed helper for the core_instance_fleet block of aws_emr_cluster (derived from provider schema).

EmrManagedScalingPolicyComputeLimits: Typed helper for the compute_limits block of aws_emr_managed_scaling_policy (derived from provider schema).
EmrSecurityConfigurationName: At most one of name, name_prefix on aws_emr_security_configuration: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
EmrSecurityConfigurationNameChoice: The EmrSecurityConfigurationName.name choice: sets name.
EmrSecurityConfigurationNamePrefix: The EmrSecurityConfigurationName.namePrefix choice: sets name_prefix.
EmrStudioSessionMappingIdentity: Exactly one of identity_id, identity_name on aws_emr_studio_session_mapping: the provider rejects none and more than one, so each variant sets one of them.
EmrStudioSessionMappingIdentityId: The EmrStudioSessionMappingIdentity.identityId choice: sets identity_id.
EmrStudioSessionMappingIdentityName: The EmrStudioSessionMappingIdentity.identityName choice: sets identity_name.
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.

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.
