DianaConfig class

Configuration store backed by flattened dot-separated keys, with environment-variable overrides.

Sources, highest precedence first:

1. Environment variables (server.port ← SERVER_PORT)
2. The YAML file loaded by DianaConfig.load (nested maps flattened to dot keys)

Constructors

DianaConfig(Map<String, Object?> values, {Map<String, String>? environment, List<String> activeProfiles = const []})

Creates a config from already-flattened dot-keys (e.g. {'server.port': 8080}). Pass environment to enable env overrides (tests can inject a fake map).

DianaConfig.empty()

An empty configuration.

const

Properties

activeProfiles → List<String>

Profiles applied by load (empty for hand-built configs).

final

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

contains(String key) → bool

Whether key is present in any configuration source.

get<T>(String key, {T? defaultValue}) → T

Returns the value for key coerced to T (String, int, double, bool or num).

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

section(String prefix) → Map<String, Object?>

The flattened keys under prefix., with the prefix stripped and environment overrides applied.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Methods

envNameFor(String key) → String

The environment variable that overrides key: upper-cased with dots and dashes replaced by underscores (server.port → SERVER_PORT).

load(String path, {Map<String, String>? environment}) → Future<DianaConfig>

Loads path (YAML), applies profile overlays and overlays Platform.environment. A missing file yields an env-only configuration, so containerized deployments can run on environment variables alone.
