+
+A new Flutter project.
+
+## Getting Started
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+
+For help getting started with Flutter development, view the
+[online documentation](https://docs.flutter.dev/), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.

+# This file configures the analyzer, which statically analyzes Dart code to
+# check for errors, warnings, and lints.
+#
+# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
+# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
+# invoked from the command line by running `flutter analyze`.
+
+# The following line activates a set of recommended lints for Flutter apps,
+# packages, and plugins designed to encourage good coding practices.

+  # The lint rules applied to this project can be customized in the
+  # section below to disable rules from the `package:flutter_lints/flutter.yaml`
+  # included above or to enable additional rules. A list of all available lints
+  # and their documentation is published at https://dart.dev/lints.
+  #
+  # Instead of disabling a lint rule for the entire project in the
+  # section below, it can also be suppressed for a single line of code
+  # or a specific dart file by using the `// ignore: name_of_lint` and
+  # `// ignore_for_file: name_of_lint` syntax on the line or in the file
+  # producing the lint.

+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

+///  A Timestamp represents a point in time independent of any time zone or local
+///  calendar, encoded as a count of seconds and fractions of seconds at
+///  nanosecond resolution. The count is relative to an epoch at UTC midnight on
+///  January 1, 1970, in the proleptic Gregorian calendar which extends the
+///  Gregorian calendar backwards to year one.
+///
+///  All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+///  second table is needed for interpretation, using a [24-hour linear
+///  smear](https://developers.google.com/time/smear).
+///
+///  The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+///  restricting to that range, we ensure that we can convert to and from [RFC
+///  3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+///
+///  # Examples
+///
+///  Example 1: Compute Timestamp from POSIX `time()`.
+///
+///      Timestamp timestamp;
+///      timestamp.set_seconds(time(NULL));
+///      timestamp.set_nanos(0);
+///
+///  Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+///
+///      struct timeval tv;
+///      gettimeofday(&tv, NULL);
+///
+///      Timestamp timestamp;
+///      timestamp.set_seconds(tv.tv_sec);
+///      timestamp.set_nanos(tv.tv_usec * 1000);
+///
+///  Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+///
+///      FILETIME ft;
+///      GetSystemTimeAsFileTime(&ft);
+///      UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+///
+///      // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+///      // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+///      Timestamp timestamp;
+///      timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+///      timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+///
+///  Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+///
+///      long millis = System.currentTimeMillis();
+///
+///      Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+///          .setNanos((int) ((millis % 1000) * 1000000)).build();
+///
+///  Example 5: Compute Timestamp from Java `Instant.now()`.
+///
+///      Instant now = Instant.now();
+///
+///      Timestamp timestamp =
+///          Timestamp.newBuilder().setSeconds(now.getEpochSecond())
+///              .setNanos(now.getNano()).build();
+///
+///  Example 6: Compute Timestamp from current time in Python.
+///
+///      timestamp = Timestamp()
+///      timestamp.GetCurrentTime()
+///
+///  # JSON Mapping
+///
+///  In JSON format, the Timestamp type is encoded as a string in the
+///  [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+///  format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+///  where {year} is always expressed using four digits while {month}, {day},
+///  {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+///  seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+///  are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+///  is required. A proto3 JSON serializer should always use UTC (as indicated by
+///  "Z") when printing the Timestamp type and a proto3 JSON parser should be
+///  able to accept both UTC and other timezones (as indicated by an offset).
+///
+///  For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+///  01:30 UTC on January 15, 2017.
+///
+///  In JavaScript, one can convert a Date object to this format using the
+///  standard
+///  [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+///  method. In Python, a standard `datetime.datetime` object can be converted
+///  to this format using
+///  [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+///  the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+///  the Joda Time's [`ISODateTimeFormat.dateTime()`](
+///  http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime()
+///  ) to obtain a formatter capable of generating timestamps in this format.

+// A Timestamp represents a point in time independent of any time zone or local
+// calendar, encoded as a count of seconds and fractions of seconds at
+// nanosecond resolution. The count is relative to an epoch at UTC midnight on
+// January 1, 1970, in the proleptic Gregorian calendar which extends the
+// Gregorian calendar backwards to year one.
+//
+// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+// second table is needed for interpretation, using a [24-hour linear
+// smear](https://developers.google.com/time/smear).
+//
+// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+// restricting to that range, we ensure that we can convert to and from [RFC
+// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+//
+// # Examples
+//
+// Example 1: Compute Timestamp from POSIX `time()`.
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(time(NULL));
+//     timestamp.set_nanos(0);
+//
+// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+//
+//     struct timeval tv;
+//     gettimeofday(&tv, NULL);
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(tv.tv_sec);
+//     timestamp.set_nanos(tv.tv_usec * 1000);
+//
+// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+//
+//     FILETIME ft;
+//     GetSystemTimeAsFileTime(&ft);
+//     UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+//
+//     // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+//     // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+//     Timestamp timestamp;
+//     timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+//     timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+//
+// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+//
+//     long millis = System.currentTimeMillis();
+//
+//     Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+//         .setNanos((int) ((millis % 1000) * 1000000)).build();
+//
+// Example 5: Compute Timestamp from Java `Instant.now()`.
+//
+//     Instant now = Instant.now();
+//
+//     Timestamp timestamp =
+//         Timestamp.newBuilder().setSeconds(now.getEpochSecond())
+//             .setNanos(now.getNano()).build();
+//
+// Example 6: Compute Timestamp from current time in Python.
+//
+//     timestamp = Timestamp()
+//     timestamp.GetCurrentTime()
+//
+// # JSON Mapping
+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required. A proto3 JSON serializer should always use UTC (as indicated by
+// "Z") when printing the Timestamp type and a proto3 JSON parser should be
+// able to accept both UTC and other timezones (as indicated by an offset).
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard
+// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using
+// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+// the Joda Time's [`ISODateTimeFormat.dateTime()`](
+// http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime()
+// ) to obtain a formatter capable of generating timestamps in this format.
+//
+message Timestamp {
+  // Represents seconds of UTC time since Unix epoch
+  // 1970-01-01T00:00:00Z. Must be from 0001-01-01T00:00:00Z to
+  // 9999-12-31T23:59:59Z inclusive.
+  int64 seconds = 1;
+
+  // Non-negative fractions of a second at nanosecond resolution. Negative
+  // second values with fractions must still have non-negative nanos values
+  // that count forward in time. Must be from 0 to 999,999,999
