Implementation of Route Preview + Preference Screen

[csbduzi]

General Information

• The route preview screen is a screen that will display a preview path from one point to another between two makers on a outdoor map.

• The preview screen will be accompanied of a bottom menu that will display the important information such as the method of transportation and the time to arrival to get to the destination.

• From the bottom menu, there will be an arrow-up button, where the user will have the option to press on it, to make the preference page appear.

• On the preference page, the user will have the option to choose from transportation method, pick the type of user that represents him/her and indicate whether his/her mobility is reduced for appropriate accommodation. By changing those settings, the traced route on the outdoor map or on the indoor building map will change accordingly.

Preference Menu has to be implemented properly. As of now, we can't fetch the value to the Preview Screen.

The preferences screen has been implemented with a simple and unencrypted key-value storage (AsyncStorage) for the persistence and retrieval of values by other screens. The buttons on the PreferenceMenu will have states and whenever a change is recorded by the AsyncStorage, the PreviewDirection screen will be be able to retrieve the values of the buttons.

Here is a sneak peek of the Preference Screen:
