74 | 75 | 76 | ## Getting Started 77 | 78 | 1.add dependencies into you project pubspec.yaml file: 79 | ``` 80 | flutter_custom_calendar: 81 | git: 82 | url: https://github.com/LXD312569496/flutter_custom_calendar.git 83 | ``` 84 | 85 | 2.import flutter_custom_calendar lib 86 | ``` 87 | import 'package:flutter_custom_calendar/flutter_custom_calendar.dart'; 88 | ``` 89 | 90 | 3.create CalendarViewWidget object，profile CalendarController 91 | ``` 92 | CalendarController controller= new CalendarController( 93 | minYear: 2018, 94 | minYearMonth: 1, 95 | maxYear: 2020, 96 | maxYearMonth: 12, 97 | showMode: CalendarConstants.MODE_SHOW_MONTH_AND_WEEK); 98 | CalendarViewWidget calendar= CalendarViewWidget( 99 | calendarController: controller, 100 | ), 101 | ``` 102 | 103 | 4.operate controller 104 | ``` 105 | controller.toggleExpandStatus();//Switch between month view and week view 106 | ``` 107 | 108 | ``` 109 | controller.previousPage();//Action calendar switch to previous page 110 | ``` 111 | 112 | ``` 113 | controller.nextPage();//Action calendar switch to next page 114 | 115 | ``` 116 | 117 | 118 | ## 2.0 version 119 | Major changes： 120 | * The UI configuration related parameters are moved to the calendar view construction method (the old version is configured in the controller) 121 | * Calendar supports padding and margin attributes, and item size calculation and modification. 122 | * Realize the overall adaptive height of calendar 123 | * The controller provides the method of changing extradatamap, which can dynamically modify the customized data extradatamap at any time. 124 | * It supports the display of monthly view and weekly view, with weekly view as the priority, and mode "show" week "and" month " 125 | * Supports verticalspacing and itemsize properties 126 | 127 | 128 | ## matters needing attention 129 | 130 | * If you use the version before 2.0, you need to move the UI configuration related parameters to the calendar view construction method (the old version is configured in the controller). 131 | * I haven't found any other problems for the time being. If you have any, please let me know. 132 | * If you use this library to make a calendar, you can share the display results with me, and I will paste them on the document for display. 133 | 134 | 135 | 136 | ## API Documentation 137 | 138 | [API Documentation](API.md) 139 | 140 | 141 | -------------------------------------------------------------------------------- /example/.idea/codeStyles/Project.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 7 | 8 | 9 |
