Hi, We need to create a set of screen widgets for our existing flutter app in order to have on the screen of the mobile device Android/iOS that has installed our app. The widgets must show visual the: Notifications, the reminders, the appointments, the tasks, the leads, the emails received, the sms received, notes, billing, consent forms. From the widgets area we must be able to: - create an appointment - create a task - create a contact - create a lead - create a notes - send an email - send an sms The widgets should also add the appointments received in the application directly in the calendar of the smartphone. The widgets should also be able to sync the tasks from the app with the ones from the phone and add a due date and time in the calendar. The widgets should also sync the leads and contacts of the app with the ones from the phone. The widgets should also be able to send an sms reminder using the sms option from the phone. The widgets should also be able to create folders with each customer id from the app into the phone and sync the pictures taken with the phone with the customer files in the app when the button from the widgets area to add files has been used. The widgets should also be able to send an email reminder using the email option from the phone. The widgets should also recognize when a contact/lead from the phone agenda is calling and show that name of the screen with the option to open that customer profile in the app . Basically a 2-way sync between all the actions in the phone and the app using the new widgets. We need to see your portfolio also that you have created these set of widgets before. Happy bidding!
