WasmRuntime class abstract interface

A loaded ffmpeg.wasm instance with its in-memory virtual file system.

This is the browser-side counterpart to ProcessRunner: the one seam between WasmFfmpegRunner and JavaScript. CI exercises the full provider logic on the VM against a mock of this contract; the real JS-interop binding lives in the conditional wasm_runtime_bindings and only runs in the manual, wasm-tagged browser harness.

Properties

hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

exec(List<String> args) → Future<int>
Runs one FFmpeg invocation with the argument array args and completes with its exit code (0 means success).
load() → Future<void>
Loads the wasm module (fetching and compiling it). Idempotency is the caller's job — the provider calls this exactly once per runtime.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
readFile(String name) → Future<Uint8List>
Reads the file name back out of the virtual file system.
toString() → String
A string representation of this object.
inherited
writeFile(String name, Uint8List bytes) → Future<void>
Writes bytes into the runtime's virtual file system as name.

Operators

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