Methods

create(LLMConfig config) → T

Create a provider instance from the given configuration

override

createProviderSafely<P>(LLMConfig config, P configFactory(), T providerFactory(P)) → T

Helper method for creating provider instances with error handling

getBaseConfigMap(LLMConfig config) → Map<String, dynamic>

Common configuration transformation for basic parameters This handles the most common config fields that most providers use

getDefaultConfig() → LLMConfig

Create default config with provider-specific defaults Subclasses should override getProviderDefaults() to customize

override

getExtension<E>(LLMConfig config, String key, [E? defaultValue]) → E?

Helper method to safely get extensions with type checking

getProviderDefaults() → Map<String, dynamic>

Provider-specific default values Subclasses must implement this to provide their defaults

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

validateApiKey(LLMConfig config) → bool

Common API key validation Most providers require an API key

validateConfig(LLMConfig config) → bool

Default validation that checks for API key presence Override this method for providers with different requirements

override

validateConfigWithDetails(LLMConfig config) → void

Enhanced validation with detailed error messages

validateModelOnly(LLMConfig config) → bool

Validation for providers that don't require API key (like Ollama)

Operators

operator ==(Object other) → bool

The equality operator.
