on → Events

read-only, inherited

This is an ease-of-use accessor for event streams which should only be used when an explicit accessor is not available.

onAbort → Stream<ProgressEvent>

read-only

Stream of abort events handled by this FileReader.

onError → Stream<ProgressEvent>

read-only

Stream of error events handled by this FileReader.

onLoad → Stream<ProgressEvent>

read-only

Stream of load events handled by this FileReader.

onLoadEnd → Stream<ProgressEvent>

read-only

Stream of loadend events handled by this FileReader.

onLoadStart → Stream<ProgressEvent>

read-only

Stream of loadstart events handled by this FileReader.

onProgress → Stream<ProgressEvent>

read-only

Stream of progress events handled by this FileReader.

readyState → int

read-only

result → Object?

read-only

runtimeType → Type

read-only, inherited

A representation of the runtime type of the object.

Methods

abort() → void

addEventListener(String type, EventListener? listener, [bool? useCapture]) → void

inherited

dispatchEvent(Event event) → bool

inherited

noSuchMethod(Invocation invocation) → dynamic

inherited

Invoked when a non-existent method or property is accessed.

readAsArrayBuffer(Blob blob) → void

readAsDataUrl(Blob blob) → void

@JSName('readAsDataURL')

readAsText(Blob blob, [String? label]) → void

inherited

toString() → String

inherited

A string representation of this object.

Operators

operator ==(Object other) → bool

inherited

The equality operator.

Constants
