NativeImplementations class abstract

provides native implementations for demanding arithmetic operations in order to prevent the UI from blocking

possible implementations might be:

• native code
• another Dart isolate
• a web worker
• a dummy implementations

Rules for extension (important for noSuchMethod implementations)

• always only accept exactly one positioned argument
• catch the corresponding case in NativeImplementations.noSuchMethod
• always write a dummy implementations

Implementers

• NativeImplementationsDummy
• NativeImplementationsIsolate
• NativeImplementationsWebWorker

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

calcImageMetadata(Uint8List bytes, {bool retryInDummy = false}) → FutureOr<SDNImageFileResizedResponse?>

decryptFile(EncryptedFile file, {bool retryInDummy = true}) → FutureOr<Uint8List?>

generateUploadKeys(GenerateUploadKeysArgs args, {bool retryInDummy = true}) → FutureOr<RoomKeys>

keyFromPassphrase(KeyFromPassphraseArgs args, {bool retryInDummy = true}) → FutureOr<Uint8List>

noSuchMethod(Invocation invocation) → dynamic

this implementation will catch any non-implemented method

override

shrinkImage(SDNImageFileResizeArguments args, {bool retryInDummy = false}) → FutureOr<SDNImageFileResizedResponse?>

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Constants

dummy → const NativeImplementationsDummy

a dummy implementation executing all calls in the same thread causing the UI to likely freeze
