IdleSource class abstract

A single way of reading the Idle duration — milliseconds since the user's last keyboard or mouse input — directly from the operating system.

Deliberately synchronous: an FFI call into the OS is a plain function call, so there is no await and therefore no resume point at which monitoring state could have changed underneath us. (That hazard is why the method-channel path needs the generation counter — see docs/agents/lessons.md.) The asynchronous FlutterInactiveTimerPlatform.getIdleDuration contract is preserved by the adapter, not by this type; see ADR-0003 and ADR-0004.

A source returns one already-computed value rather than raw clock readings, per ADR-0001 — the wraparound-prone subtraction stays on the side of the boundary where it is naturally correct.

Properties

hashCode → int
The hash code for this object.
no setterinherited
isSupported → bool
Whether this source can actually read the OS on the current platform.
no setter
name → String
Human-readable identifier, e.g. windows/GetLastInputInfo. Shown in the example's parity screen and used to label parity-test failures, so it must identify which binding a failure came from.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

idleMilliseconds() → int
The Idle duration in milliseconds.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
override

Operators

operator ==(Object other) → bool
The equality operator.
