Get Flutter rendering performance info
AI agents call get_flutter_performance_overlay to retrieve information from Enhanced ADB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves Flutter performance metrics and rendering information from a running app. It does not modify app state, execute arbitrary code, delete data, or move money. It is a diagnostic/observational operation that gathers telemetry.
From the tool's definition Tool name 'get_flutter_performance_overlay' and description 'Get Flutter rendering performance info' indicate data retrieval without modification. The verb 'Get' and 'performance info' (retrieval of metrics/telemetry) are characteristic of Read operations.
