Interpreter class
Web implementation of Interpreter.
Uses the TFLite.js WASM runtime for inference. The supported subset of the
API (fromAsset, fromBytes, run, runForMultipleInputs, and the tensor
getters) matches the native Interpreter, so common inference code needs no
conditional branching. Native-only members (fromFile, fromBuffer,
fromAddress, resizeInputTensor, the signature-runner and variable-tensor
APIs, and address) throw UnsupportedError on web.
Constructors
- Interpreter.fromAddress(int address, {bool allocated = true, bool deleted = false})
-
Not supported on web (no pointer addresses).
factory
- Interpreter.fromBuffer(Uint8List buffer, {InterpreterOptions? options})
-
Not supported on web.
factory
- Interpreter.fromFile(dynamic modelFile, {InterpreterOptions? options})
-
Not supported on web. Use fromAsset or fromBytes instead.

Methods
-
allocateTensors(
) → void - No-op on web (TFLite.js handles allocation internally).
-
close(
) → void - Closes the interpreter.
-
getInputIndex(
String opName) → int - Gets index of an input given the op name.
-
getInputTensor(
int index) → Tensor - Gets the input Tensor for the provided input index.
-
getInputTensors(
) → List< Tensor> - Gets input tensors (metadata-only on web).
-
getOutputIndex(
String opName) → int - Gets index of an output given the op name.
-
getOutputTensor(
int index) → Tensor - Gets the output Tensor for the provided output index.
-
getOutputTensors(
) → List< Tensor> - Gets output tensors.
-
getSignatureKey(
int index) → String - Not supported on web.
-
getSignatureRunner(
String signatureKey) → SignatureRunner - Not supported on web.
-
getVariableTensor(
int index) → Tensor - Not supported on web.
-
getVariableTensorCount(
) → int - Returns 0 on web (no variable tensor support).
-
invoke(
) → void - No-op on web (inference is done through run/runForMultipleInputs).
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
resetVariableTensors(
) → void - No-op on web.
-
resizeInputTensor(
int tensorIndex, List< int> shape) → void - Not supported on web, TFLite.js does not expose a tensor resize API.
-
run(
Object input, Object output) → void - Run inference for single input and output.
-
runForMultipleInputs(
List< Object> inputs, Map<int, Object> outputs) → void - Run inference for multiple inputs and outputs.
-
runInference(
List< Object> inputs) → void - Runs inference by converting inputs to JS tensors and calling predict.
-
toString(
) → String -
A string representation of this object.

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

Static Methods
-
fromAsset(
String assetName, {InterpreterOptions? options}) → Future< Interpreter> - Creates interpreter from an asset name.
-
fromBytes(
Uint8List buffer, {InterpreterOptions? options}) → Future< Interpreter> - Creates interpreter from raw bytes (async web-compatible version).
