Using the latest flutter version under Android Studio. 

Main dart page got numerous errors - See below link

The entire code (Which contained several pages)listed below in url-

The first one -

import 'package:flutter/material.dart';

What is wrong with that line above?
URL doesn't exist not sure why because it used to work before. For some reason it can't find the package

TextStyle(fontWeight: FontWeight.bold, fontSize: 13, color: Colors.black);
TextStyle not define (huh)? Was working before as well.
The rest of the required create class.
Are you guys able to resolve these error messages?

Return value is missing see attachment on the bottom of this page.

Here is the full code and the screenshot below the full code. Also when putting in the answer can you put in the full code. Because I put in the previous answers I still got error messages.

Fill in the blank with the vocabulary term that best fits the following description.

___________________________ Substances in plants that have a positive effect on health and vitality

___________________________ Substances in animals, such as egg yolks, that provide health benefits beyond traditional nutrients

___________________________ Food or food ingredients that are thought possess a beneficiary effect beyond just what micronutrients and macronutrients do

___________________________ Claim made on a food and dietary supplement label that describes a relationship between a food substance and reduced risk of a disease.

___________________________ Live microorganism that can be consumed, in either a supplement or certain foods, that colonizes the body. It is especially important in colonizing the large intestine and balancing out the gut flora.

___________________________ The live microorganisms of the digestive tract need these nondigestable food components to stimulate growth.

___________________________ Type of fiber found only in plants that is made up of nondigestible carbohydrates and lignins.

___________________________ Type of fiber that is isolated, extracted or synthesized and most likely has a beneficial physiological effect in humans.

___________________________ A fat that contains the maximum number of hydrogen possible and no carbon-carbon bonds.

___________________________ A type of passive uptake or transport in the bod that moves soluates from an area of higher concentration to an area of lower concentration without the help of a carrier molecule such as protein.

“We are observing wasted heat in everyday life for example in Pakistan heavy generated are installed, during their supply of electricity an excessive amount of wasted heat is produced in its surrounding, similarly when we drive a vehicle a heat is available in the surrounding of engine of that vehicle, we can also see many more such examples of wastage of heat.

a. Identify the dangers of passive smoke.

b. Do you know of a situation where you were forced to breathe passive smoke?

c. What do you think should be done about passive smoke in public places?

d. How would you address someone who was exposing you, a member of your family, or a friend to passive smoke?

Blood is the transport medium in our bodies. Its special function is to make sure all the tissues receive needed nutrients for survival. It becomes apparent, then, that all components of blood need to be assembled correctly in order for this important transport fluid to function. There is a unique location for the creation of blood that helps to protect the process of hematopoiesis.

1. Where in the adult human body are is/are the blood made/created? Be specific (name specific locations in the body).

2. How does the newly created blood get from its place of origin to the rest of the body? Erythropoiesis, the process of creating red blood cells has its own unique requirements in order to complete the process correctly.

3. What 3 food nutrients (other than the required macronutrients [proteins/carbohydrates]) are
essential for the production of red blood cells? (Hint: all 3 are in the micronutrient category).

4. Highlight all the factors that would serve as a stimulus for erythropoiesis:
a) hemorrhage 

b) insufficient hemoglobin per RBC

c) living at a high altitude

d) breathing pure oxygen

5. What makes blood red? Blood can be either a bright scarlet red or a dark brick red. What creates the difference between the two colors of blood? Can either color indicate an anemia?

6. The process of creating new erythrocytes is under the direction of a hormone, erythropoietin. Where is erythropoietin synthesized and released? What cells are created that will then become mature erythrocytes?

7. Define anemia. Be sure to include the 2 general causes of anemia.              

8. There is a type of anemia that occurs from acute blood loss, i.e. from trauma where the internal environment has been exposed to the outside environment. Name this type of anemia. Explain how this type of anemia would be determined by laboratory analysis.

9. Women in their childbearing years are particularly susceptible to one type of anemia. Name
this type of anemia, its causes and list treatment protocols.

10. Intrinsic factor is protein produced by specific cells (parietal cells) in the lining of the stomach. The elderly tend to have a decreased efficiency of the gastric mucosa (stomach lining) and may end up with another type of anemia, associated with the lack of intrinsic factor. Name this anemia. What is important about intrinsic factor? Why does it contribute to a type of anemia?
