cloud_functions library

Cloud Functions Gen 2 — serverless function execution with build + deploy from source.

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.
Cloudfunctions2FunctionAutomaticUpdatePolicy
Typed helper for the build_config.automatic_update_policy block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionAutomaticUpdatePolicyChoice
The Cloudfunctions2FunctionUpdatePolicy.automaticUpdatePolicy choice: sets automatic_update_policy.
Cloudfunctions2FunctionBuildConfig
Typed helper for the build_config block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionConnection
At most one of vpc_connector, direct_vpc_network_interface on the service_config block of google_cloudfunctions2_function: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
Cloudfunctions2FunctionConnectionDirectVpcNetworkInterface
The Cloudfunctions2FunctionConnection.directVpcNetworkInterface choice: sets direct_vpc_network_interface.
Cloudfunctions2FunctionConnectionVpcConnector
The Cloudfunctions2FunctionConnection.vpcConnector choice: sets vpc_connector.
Cloudfunctions2FunctionDirectVpcNetworkInterface
Typed helper for the service_config.direct_vpc_network_interface block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionEventFilters
Typed helper for the event_trigger.event_filters block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionEventTrigger
Typed helper for the event_trigger block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionIamBindingCondition
Typed helper for the condition block of google_cloudfunctions2_function_iam_binding (derived from provider schema).
Cloudfunctions2FunctionIamMemberCondition
Typed helper for the condition block of google_cloudfunctions2_function_iam_member (derived from provider schema).
Cloudfunctions2FunctionOnDeployUpdatePolicy
Typed helper for the build_config.on_deploy_update_policy block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionOnDeployUpdatePolicyChoice
The Cloudfunctions2FunctionUpdatePolicy.onDeployUpdatePolicy choice: sets on_deploy_update_policy.

Typed helper for the build_config.source.repo_source block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionRepoSourceChoice
The Cloudfunctions2FunctionSource.repoSource choice: sets repo_source.
Cloudfunctions2FunctionRevision
Exactly one of branch_name, tag_name, commit_sha on the build_config.source.repo_source block of google_cloudfunctions2_function: the provider rejects none and more than one, so each variant sets one of them.
Cloudfunctions2FunctionRevisionBranchName
The Cloudfunctions2FunctionRevision.branchName choice: sets branch_name.
Cloudfunctions2FunctionRevisionCommitSha
The Cloudfunctions2FunctionRevision.commitSha choice: sets commit_sha.
Cloudfunctions2FunctionRevisionTagName
The Cloudfunctions2FunctionRevision.tagName choice: sets tag_name.
Cloudfunctions2FunctionSecretEnvironmentVariables
Typed helper for the service_config.secret_environment_variables block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionSecretVolumes
Typed helper for the service_config.secret_volumes block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionServiceConfig
Typed helper for the service_config block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionSource
Exactly one of storage_source, repo_source on the build_config.source block of google_cloudfunctions2_function: the provider rejects none and more than one, so each variant sets one of them.
Cloudfunctions2FunctionStorageSource
Typed helper for the build_config.source.storage_source block of google_cloudfunctions2_function (derived from provider schema).
Cloudfunctions2FunctionStorageSourceChoice
The Cloudfunctions2FunctionSource.storageSource choice: sets storage_source.
Cloudfunctions2FunctionUpdatePolicy
Exactly one of automatic_update_policy, on_deploy_update_policy on the build_config block of google_cloudfunctions2_function: the provider rejects none and more than one, so each variant sets one of them.
Cloudfunctions2FunctionVersions
Typed helper for the service_config.secret_volumes.versions block of google_cloudfunctions2_function (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.
DataGoogleCloudfunctions2Function
Factory wrapper for google_cloudfunctions2_function.
DataGoogleCloudfunctions2FunctionIamPolicy
Factory wrapper for google_cloudfunctions2_function_iam_policy.
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.
GoogleCloudfunctions2Function
Factory wrapper for google_cloudfunctions2_function.
GoogleCloudfunctions2FunctionIamBinding
Factory wrapper for google_cloudfunctions2_function_iam_binding.
GoogleCloudfunctions2FunctionIamMember
Factory wrapper for google_cloudfunctions2_function_iam_member.
GoogleCloudfunctions2FunctionIamPolicy
Factory wrapper for google_cloudfunctions2_function_iam_policy.
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.

Extension Types

DirectVpcEgress
service_config.direct_vpc_egress -- egress policy for direct VPC network interfaces. Server default is vpcEgressPrivateRangesOnly.
EventTriggerRetryPolicy
event_trigger.retry_policy -- behaviour when the user code raises. retry re-delivers per the system retry budget; doNotRetry drops on first failure; unspecified defers to the server default (currently doNotRetry).
IngressSettings
service_config.ingress_settings -- which traffic sources can invoke the underlying Cloud Run service. Defaults server-side to allowAll.
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, ...).
VpcConnectorEgressSettings
service_config.vpc_connector_egress_settings -- egress policy when the function attaches via a Serverless VPC Access connector (Cloudfunctions2FunctionServiceConfig.vpcConnector). Mutually exclusive in spirit with DirectVpcEgress (which applies when using direct VPC egress).

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.
