LDContextBuilder class final

A builder to facilitate the creation of LDContexts. Note that the return type of kind is a LDAttributesBuilder that is used to define attributes for the specific kind of context you are creating.

LDContextBuilder builder = LDContextBuilder();
builder.kind('user', 'user-key-123abc')
  .name('Sandy Smith')
  .setString('employeeID', 'ID-1234');
builder.kind('company', 'company-key-123abc')
  .name('ExampleCompany');
builder.kind('options', 'options-key-123abc')
  .setValue('advanced', LDValue.buildObject().addBool('poweruser', true).build())
LDContext context = builder.build();

Methods

build() → LDContext

Builds the context.

kind(String kind, [String? key]) → LDAttributesBuilder

Adds another kind to the context. kind and optional key must be non-empty. Calling this method again with the same kind returns the same LDAttributesBuilder as before.

mergeContext(LDContext context) → LDContextBuilder

Adds a context to the context builder combining the provided context kinds with the existing kinds in the builder. This function is not normally needed as the kind method can be used for making a multi-context.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
