From the beginning, Flutter was a great encounter. Building an engaging user interface has never been faster. Whether you are an amateur or an educated developer, it's not difficult to be hopelessly infatuated with fluent. All software developers understand that dates are the toughest thing. Similarly, the timetable is not an exception.

In mobile applications, there are many cases where users need to enter a date of birth, book air tickets, arrange meetings, and so on.

In this article, we will explore custom time planning Flutter. We will also implement a demo program and create a customizable time plan using the time planner package in your Flutter application.

https://pub.dev/packages/time_planner

Introduction

A pleasant, simple use, customized time planning for Flutter mobile, desktop and network. This is a widget that displays tasks to customers on a schedule. Each row displays an hour and each column displays a day, but you can change the title of the section and display anything else you need.

This demo video shows how to create a customizable schedule in fluent. It shows how a customized schedule will work using your Flutter application's schedule package. It shows that a random time planner will be created when the user clicks on any row or column. Animated. It will be displayed on your device.

attribute

The time planner has the following properties:

startHour: this attribute is used to start the time from this. It will start from 1
endHour: this property is used for the end of this time. The maximum value is 24
headers: this attribute is used to create days. Every day is a timeplanertitle. You should create at least one day
tasks: this attribute is used to list widgets on the time planner
Style: this attribute is used for the style of the scheduler
currentTimeAnimation: this property is used to scroll the widget load to the current time of the animation. The default value is true

Implementation

Step 1: add dependencies

Add dependencies to the pubspec(yaml file.

time_planner: ^0.0.3

Step 2: Import

import 'package:time_planner/time_planner.dart';

Step 3: run the fluent package in the root directory of the application.

code

You need to implement it in your code:

In the lib folder, create a file named main New dart file for dart.

First, we create a timeplanner task list called variable task.

List<TimePlannerTask> tasks = [];

We will create a_ addobject() method.

void _addObject(BuildContext context) {
  List<Color?> colors = [
    Colors.purple,
    Colors.blue,
    Colors.green,
    Colors.orange,
    Colors.cyan
  ];

  setState(() {
    tasks.add(
      TimePlannerTask(
        color: colors[Random().nextInt(colors.length)],
        dateTime: TimePlannerDateTime(
            day: Random().nextInt(10),
            hour: Random().nextInt(14) + 6,
            minutes: Random().nextInt(60)),
        minutesDuration: Random().nextInt(90) + 30,
        daysDuration: Random().nextInt(4) + 1,
        onTap: () {
          ScaffoldMessenger.of(context).showSnackBar(
              SnackBar(content: Text('You click on time planner object')));
        },
        child: Text(
          'this is a demo',
          style: TextStyle(color: Colors.grey[350], fontSize: 12),
        ),
      ),
    );
  });

  ScaffoldMessenger.of(context).showSnackBar(
      SnackBar(content: Text('Random task added to time planner!')));
}

In the function, we will add tasks Add() method. Internally, we will add the timeplanertask () widget. In this widget, we will add color, date time, minutesDuration and daysDuration. We will also display the snapbar message when the user clicks on the time planner.

In the body, we will add the TimePlanner () widget. Internally, we will add startHour, endHour, and header. In the header file, we will add some timeplanertitle (). In addition, we will add tasks and styles.

TimePlanner(
  startHour: 2,
  endHour: 24,
  headers: [
    TimePlannerTitle(
      date: "7/20/2021",
      title: "tuesday",
    ),
    TimePlannerTitle(
      date: "7/21/2021",
      title: "wednesday",
    ),
    TimePlannerTitle(
      date: "7/22/2021",
      title: "thursday",
    ),
    TimePlannerTitle(
      date: "7/23/2021",
      title: "friday",
    ),
    TimePlannerTitle(
      date: "7/24/2021",
      title: "saturday",
    ),
    TimePlannerTitle(
      date: "7/25/2021",
      title: "sunday",
    ),
    TimePlannerTitle(
      date: "7/26/2021",
      title: "monday",
    ),
    TimePlannerTitle(
      date: "7/27/2021",
      title: "tuesday",
    ),
    TimePlannerTitle(
      date: "7/28/2021",
      title: "wednesday",
    ),
    TimePlannerTitle(
      date: "7/29/2021",
      title: "thursday",
    ),
    TimePlannerTitle(
      date: "7/30/2021",
      title: "friday",
    ),
    TimePlannerTitle(
      date: "7/31/2021",
      title: "Saturday",
    ),
  ],
  tasks: tasks,
  style: TimePlannerStyle(
      showScrollBar: true
  ),
),

Now we will create a floating actionbutton ().

floatingActionButton: FloatingActionButton(
  onPressed: () => _addObject(context),
  tooltip: 'Add random task',
  child: Icon(Icons.add),
),

When we run the application, we should get the output of the screen, just like the screenshot below.

epilogue

In this article, I have simply explained the basic structure of the Customizable Time Planner; You can modify this code according to your choice. This is a small-scale introduction to custom time planning for user interaction. From my side, it works using fluent.
