FirebasePerformancePlatform class abstract
The interface that implementations of firebase_performance must
extend.
Platform implementations should extend this class rather than implement it
as firebase_performance does not consider newly added methods to be breaking
changes. Extending this class (using extends) ensures that the subclass
will get the default implementation, while platform implementations that
implements this interface will be broken by newly added
FirebasePerformancePlatform methods.

Methods
-
delegateFor(
{required FirebaseApp app}) → FirebasePerformancePlatform -
Enables delegates to create new instances of themselves if a none default
FirebaseAppinstance is required by the user. Currently only default Firebase app only. -
isPerformanceCollectionEnabled(
) → Future< bool> - Determines whether custom performance monitoring is enabled or disabled.
-
newHttpMetric(
String url, HttpMethod httpMethod) → HttpMetricPlatform - Creates a HttpMetric object for collecting network performance data for one request/response. Only works for native apps. A stub class is created for web which does nothing.
-
newTrace(
String name) → TracePlatform - Creates a Trace object with given name. Traces can be used to measure the time taken for a sequence of steps. Traces also include “Counters”. Counters are used to track information which is cumulative in nature (e.g., Bytes downloaded).
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
setPerformanceCollectionEnabled(
bool enabled) → Future< void> - Enables or disables custom performance monitoring setup.
-
toString(
) → String -
A string representation of this object.

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

Static Properties
