core/commands/describe/describe library

Classes

DescribeAppDied: The app process died while fdb was communicating with it.
DescribeError: Generic / unrecognised error.
DescribeNoFdbHelper: fdb_helper was not detected in the running app.
DescribeRelayedError: The extension returned an error string in the error field.
DescribeResult: Result of a describeScreen invocation.
DescribeSuccess: ext.fdb.describe responded with a valid payload.
DescribeUnexpectedResponse: The VM service returned a response that is not a Map<String, dynamic>.
DescribeVmNotResponding: The app PID is alive but its VM service does not respond — typically the app is backgrounded and suspended by the OS (another app is in front).

describeEntryText(String? text) → String?: The text fdb describe shows for an interactive entry: its ·-separated parts without empty and icon-only ones (Flutter icon codepoints are in the Unicode private use area U+E000-U+F8FF). Null when nothing is left.
describeScreen(DescribeInput _) → Future<DescribeResult>: Returns a compact snapshot of the current screen via ext.fdb.describe.

DescribeInput = (): Input parameters for describeScreen. Empty record because fdb describe takes no arguments.
