antigravity 0.2.0

A native Dart client SDK for Google Antigravity, fully decoupled from the Flutter framework for server, CLI, and mobile compatibility.

0.2.0

• Model Configuration Overhaul: Replaced the monolithic GeminiConfig with a more flexible ModelTarget and polymorphic ModelEndpoint class hierarchy (GeminiAPIEndpoint, VertexEndpoint).
• Subagents Feature: Introduced SubagentConfig and SubagentCapabilities allowing definition and inclusion of subagents in the main agent's configuration.
• New Builtin Tools: Added SearchWeb tool and related SearchWebResult structured output.
• Enhanced Configuration: Support for environment variables (env) in McpStdioServer. Removed imageModel from CapabilitiesConfig to favor the new generic model targeting features.

0.1.3

• Added support for Vertex AI configuration (project, location, vertex options) in GeminiConfig.
• Refactored Model Context Protocol (MCP) server configurations to run connections natively on the Go-based harness, removing client-side McpBridge references.
• Added SlashCommand structure to input content primitives to support built-in planning flows.
• Integrated CLI Spinner into runInteractiveLoop with step-by-step progress tracking via agent.conversation.receiveSteps().
• Enhanced policy engine with a 9-level priority model supporting prefix wildcards and custom MCP policy validators.
• Added AntigravityCancelledException and AntigravityExecutionException for robust error handling.

0.0.1

• Initial release of the Antigravity Dart SDK.
