of static method

  1. @Deprecated('Use TickerMode.valuesOf to get both enabled and forceFrames. ' 'This feature was deprecated after v3.35.0-0.0.pre.')
bool of(
  1. BuildContext context
)

Whether tickers in the given subtree should be enabled or disabled.

This is used automatically by TickerProviderStateMixin and SingleTickerProviderStateMixin to decide if their tickers should be enabled or disabled.

In the absence of a TickerMode widget, this function defaults to true.

Typical usage is as follows:

// ignore: deprecated_member_use
bool tickingEnabled = TickerMode.of(context);

Implementation

@Deprecated(
  'Use TickerMode.valuesOf to get both enabled and forceFrames. '
  'This feature was deprecated after v3.35.0-0.0.pre.',
)
static bool of(BuildContext context) {
  final _EffectiveTickerMode? widget = context
      .dependOnInheritedWidgetOfExactType<_EffectiveTickerMode>();
  return widget?.enabled ?? true;
}
