我有一个模型，可以通过对此处的一组数字执行预测函数来检测糖尿病
model1 = Sequential()
model1.add(Dense(500, input_dim=8, activation='sigmoid'))
model1.add(Dense(100, activation='sigmoid'))
model1.add(Dense(2, activation='softmax'))
model1.compile(loss='mean_squared_error', optimizer='adam', metrics=['accuracy'])
model1.fit(x_train,y_train, epochs=1000, batch_size=70, validation_data=(x_test, y_test))
y_pred= model1.predict(x_test)
y_pred_prob = model1.predict_proba(x_test)
#s=round(b[0,0])
keras_file = "diabetes.h5"
keras.models.save_model(model1, keras_file)
converter = tf.lite.TFLiteConverter.from_keras_model_file(keras_file)
tflite_model = converter.convert()
open("diabetes.tflite", "wb").write(tflite_model)
#print(model.predict(np.array([[1,85,66,29,0,26.6,0.351,31]])))
我已将模型转换为 tflite 文件并将其添加到 flutter 应用程序中，现在我想(model.pretict())在 main.c 中使用预测函数。dart in flutter 所以我添加了 tflite 文件并导入了 main.dart

TextEditingController Glucose = new TextEditingController();
TextEditingController BloodPressure = new TextEditingController(); …我无法将图像作为背景上传到容器，我已将图像添加到资产文件夹中并将其添加到 pubspec.yaml 并向我显示该错误：

当我运行 flutter run 命令时会发生这种情况
