Need a flutter expert to link three flutter apps into a single flutter app

Job ID: 37814907

Budget: $150 – $300 AUD

Please read before bidding and bid only (with near accurate amount) if you are interested and can do this task. All the requirements are listed.

I need a flutter expert to combine these three ready-made apps for my needs.

1)Flutter app that convert WordPress to app
2)Directory listing app (based on WordPress as well)
and
3) flutter app that converts/wraps one info website to an app (it has a responsive design dictionary website, which is not possible with WordPress)
Please find links to all three apps here.

The best way is to use one app as a master with link dashboard icons in the home screen (like super app), and users are taken to other apps when clicked.

You may be able to combine apps 1 and 2 or use only one (based on your skill).

The apps can run independently (internally), or the colour scheme/interface may change for now when switched to another app (they do not need the same design in all). Still, the only condition is that it should have a common login (when a user registers, a user may be created in all systems databases with the same username and password). It should not ask logged-in users to log in again when switching apps (there is NO need to access other info between the apps now).

You do not need to combine code, but make sure that the user will install only one app (and it is not hyperlinking the other two apps). May be have it as separate folders in one flutter project. it should have one package name or it will be deployed as only one app.

For 3rd, the app converts the web to an app (which may use WebView); you may need to tweak the flutter design, like placement of buttons, etc., to make it professional.

Instead of making the user install three apps (for the same niche), I want the user to install just one app.

There may not be much coding but using efficient ideas/plans to accomplish it may not be complex for an expert.

You do not need to submit it to the Play Store and App Store but may need help resolving the problem if they reject it (but not inside those three apps).

These are all apps written in flutter, and you can check the demo video or screenshots provided in the link file.

All the requirements are included. PLEASE READ THE REQUIREMENT and put the correct amount (tentative) on which you can feel you can complete the task. Please don't quote 5-8 times after bidding.
It must be done within the deadline—preference to those who can complete it as soon as possible. Include how many you need, and we need the task done by the period.

If you have any questions or need clarification, please ask before you apply. However, I may only respond to one interested (I feel they can do it).
