I need help to create an application using Flutter, under main.dart file, the task is to develope a simple form that a user can use to create as many instances of a particular shape. The app should look like this:

Whenever you change the values it adds a new rectangle and does the calculation based on the entered values. The reset should remove the entire table. Also, some technical requirements, the app:

1. Uses some shape class to define objects from that class
2. Has a well designed form with necessary fields and buttons
3. Displays the created shapes
4. Don't use any external packages

Rectangles Wiatia 1 Length 8 Anhiectanole Areset \begin{tabular}{|c|c|c|c|} \hline Wath & Length & Perimeter & Nese \\ \hline 5 & 5 & 20 & 25 \\ \hline 2 & 5 & 14 & 10 \\ \hline 2 & 8 & 20 & 16 \\ \hline 1 & 8 & 18 & 8 \\ \hline \end{tabular} \begin{tabular}{|l|l|l|} \hline 1 & 2 & 3 \\ \hline 4 & 5 & 6 \\ \hline 7 & 8 & 9 \\ \hline, & 0 &. \\ \hline & & \\ \hline & & \\ \hline \end{tabular}
