title: Can some help me to implement calendar widget in flutter
body: <p>Click the date range display to select a date range. Your date range stays active as you switch from one report to another. All reports compare metric values for the date range you choose to metric values from the previous period.</p>
  <p>• Select Today, Yesterday, This week, <em>Last
  7 days</em>, Last 30 days, Quarter to date, or
  Custom.
  • Select Custom to create a date range beginning and ending on the dates you select.
  User can select frequently use dates and make a tab manually.
  When you compare date ranges, Analytics uses the same day of the week to start
  each date range. For example, if you use the date range Last week Sun - Sat, then
  the comparison is the previous week of Sunday to Saturday. If you use a custom
  date range, for example, 7 days beginning on a Monday, then the comparison begins
  with the previous Monday.
  The selected date will be automatically selected at the time of login of each
  individual user.</p>
