Please retry or report in https://developers.generativeai.google/guide/troubleshooting error sdk/lib/_internal/js_dev_runtime/private/ddcruntime/errors.dart 296:3 throw packages/google_generative_ai/src/api.dart 583:54 parseGenerateContentResponse here is the code :

List<Part> parts = [TextPart(message)];
try {
if (image != null) {
parts.add(DataPart(image.extension!, image.bytes!));
}
} catch (e) {
log(e.toString());
}

my add image function is working fine: if (_selectedImage != null) { final model = GenerativeModel( model: 'gemini-pro-vision', apiKey:"your api key", );

        final imageBytes = await _selectedImage!.readAsBytes();
        final content = Content.multi([
            TextPart("your message"),
            DataPart('image/jpeg', imageBytes),
        ]);

        final response = await model.generateContent([content]);

This looks like a backend error unrelated to the SDK. Hopefully this was transient, but if this is still happening the best place to get help is at the https://developers.generativeai.google/guide/troubleshooting link form the error message.
