firebase_app_hosting library
Firebase App Hosting — Cloud Run-backed successor to classic Firebase Hosting. Backends, build artifacts, custom domains, traffic split.
Classes
-
AppConstant<
T> -
A value the Stack hands to application code as a
static constin 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 constmembers 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. - DartDefineOutput
-
An
outputwhose value is the client build's--dart-definefile, registered withStack.addDartDefineOutput. - Data
-
Base of every user-instantiable Terraform
datablock. -
DataRef<
T> -
Public for sealed pattern matching, but constructor is private — only
TfRef.data()may construct instances. - EnvironmentConstant
- The AppConstant.fromEnvironment choice.
- FirebaseAppHostingBackendCodebase
-
codebaseblock. Links the backend to a Developer Connect-managed git repository, so commits flowing into the configured branch trigger builds (seeGoogleFirebaseAppHostingTraffic.rolloutPolicy). - FirebaseAppHostingBuildCodebase
-
Typed helper for the
source.codebaseblock ofgoogle_firebase_app_hosting_build(derived from provider schema). - FirebaseAppHostingBuildContainer
-
Typed helper for the
source.containerblock ofgoogle_firebase_app_hosting_build(derived from provider schema). - FirebaseAppHostingBuildSource
-
Exactly one of
container,codebaseon thesourceblock ofgoogle_firebase_app_hosting_build: the provider rejects none and more than one, so each variant sets one of them. - FirebaseAppHostingBuildSourceCodebase
-
The FirebaseAppHostingBuildSource.codebase choice: sets
codebase. - FirebaseAppHostingBuildSourceContainer
-
The FirebaseAppHostingBuildSource.container choice: sets
container. - FirebaseAppHostingDomainRedirect
-
serve.redirectsub-block. Returns an HTTP 3xx redirect for every request hitting this domain. - FirebaseAppHostingDomainServe
-
serveblock. When omitted (the default), the domain serves the backend's live content. When set, the redirect sub-block takes over -- requests are answered with an HTTP 3xx response pointing at the configured URI. - FirebaseAppHostingTrafficRolloutPolicy
-
rollout_policyblock. Drives automated builds and rollouts off a git branch in the backend's linked Developer Connect repository. When omitted, the backend never auto-rolls out -- builds are triggered exclusively by explicit GoogleFirebaseAppHostingBuild resources. - FirebaseAppHostingTrafficRouting
-
Exactly one of
rollout_policy,targetongoogle_firebase_app_hosting_traffic: the provider rejects none and more than one, so each variant sets one of them. - FirebaseAppHostingTrafficRoutingRolloutPolicy
-
The FirebaseAppHostingTrafficRouting.rolloutPolicy choice: sets
rollout_policy. - FirebaseAppHostingTrafficRoutingTarget
-
The FirebaseAppHostingTrafficRouting.target choice: sets
target. - FirebaseAppHostingTrafficSplit
-
One entry in
target.splits. Pairs a build with the percentage of traffic it should receive. - FirebaseAppHostingTrafficTarget
-
targetblock. Manually pin the desired traffic split across builds. The state'scurrentfield eventually reconverges to this value. Split percentages must sum to 100, and per the provider's current schema each individual entry must be exactly 0 or 100 (so today this behaves as "single live build" rather than a true weighted split). - GcsBackend
-
terraform { backend "gcs" { ... } }configuration. - GoogleFirebaseAppHostingBackend
-
Factory wrapper for
google_firebase_app_hosting_backend. - GoogleFirebaseAppHostingBuild
-
Factory wrapper for
google_firebase_app_hosting_build. - GoogleFirebaseAppHostingDefaultDomain
-
Factory wrapper for
google_firebase_app_hosting_default_domain. - GoogleFirebaseAppHostingDomain
-
Factory wrapper for
google_firebase_app_hosting_domain. - GoogleFirebaseAppHostingTraffic
-
Factory wrapper for
google_firebase_app_hosting_traffic. - IgnoreAllChanges
- IgnoreChanges.all.
- IgnoreAttributes
- IgnoreChanges.of.
- IgnoreChanges
-
What
ignore_changescovers: every attribute, or the listed ones. - InvalidDartDefineOutput
-
An output of
Stack.addDartDefineOutputthat 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
lifecycleblock Terraform rejects: a data source (or one of its attributes) inreplaceTriggeredBy,allinside IgnoreChanges.of, or a condition with an empty error message. - InvalidMoveTarget
-
A
movedblock whosetonames no resource of the Stack. - InvalidTimeout
-
A negative
timeoutsduration. - LifecycleCondition
-
A
preconditionorpostconditionblock: 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 (
googleforgoogle_pubsub_topic), the one itsprovidermeta-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.replaceTriggeredBylists: a resource of the Stack or an attribute getter of one.Resourceand TfRef implement it; synth reports a data source or a data-source attribute as anInvalidLifecycle. - 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, andLocalBackend; anything else implements this interface in the caller. TheStackonly stores the value and exposes a discriminator for synth'sterraform { backend ... }emitter. - StackProvider
-
Coordination interface between
Stack(in this package) and concrete providers (e.g.GoogleProviderinterradart_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(...)ormap(...). - 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 withStack.addOutput. - TfPrimitiveType
-
string,number,boolorany. -
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.variableorvar.<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.refwhose 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
resourceblock or adatablock in Terraform JSON.
Extension Types
- AppHostingServingLocality
-
serving_locality-- where App Hosting will serve content from. Set on create; immutable thereafter (changing forces replacement).regionalStrictpins serving to the backend'slocation;globalAccesslets App Hosting replicate across its global edge fleet. - OutputEnvironment
-
The environment
Stack.outputEnvironmentreturns: 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").
Constants
- terradartManifestVariable → const String
-
The environment variable the
terradartcommand 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
envand 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
