RenderSandbox class abstract interface

Storage for one render: the frames file, the manifest, materialized encoder inputs, and the encoded output.

Two backends implement it — a file-backed sandbox under a real directory (desktop/mobile, byte-identical to writing files directly) and an in-memory sandbox (web, where the browser has no file system). The capture loop and the FfmpegRunners talk only to this interface, so the same deterministic pipeline runs on every platform.

Implementers

Properties

directoryPath → String?
The real directory path a process-based encoder runs in, or null for an in-memory sandbox (a process encoder is never selected there).
no setter
hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

create() → Future<void>
Prepares the sandbox for writing (creates the directory for a file-backed sandbox; a no-op in memory).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
openFrames(String name) → CaptureSink
Opens name for appending raw frame bytes.
readBytes(String name) → Future<Uint8List>
Reads name back as bytes.
toString() → String
A string representation of this object.
inherited
writeBytes(String name, Uint8List bytes) → Future<void>
Writes bytes to name (a materialized encoder input, or an output).
writeText(String name, String content) → Future<void>
Writes content to name as UTF-8 text (the manifest).

Operators

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