• Improved example with verbose mode and proper arguments

1.0.8 12/10/25

• Fixed some issues with null check operators and error handling

1.1.0 12/11/25

• Added DexcomUpdateStatus and onStatusUpdate for Dexcom, so you can know when we start fetching the account ID, session ID, glucose data, etcetera.
• Added toJson and fromJson on some objects.
• Fixed some issues with refreshing and timing.

Note: Update to this version at your own risk. This version may be unstable.

1.1.2 12/13/25

• Fix bug with timer resetting to 0 on every refresh, regardless if we get new data or not.

1.1.3 12/15/25

• Fix another bug where the package would request too fast and get rate-limited.
  • I never noticed this because Realtek WiFi cards are bad heh
• Apparently even with the above fix it can still get rate-limited? So I added a 30-second wait if we get rate-limited.
• Added code property to DexcomGlucoseRetrievalException.
• The readme is now like 3x as long. This is because I merged my two readmes for this project.
• Some other bug fixes and improvements.

Note: There is currently an issue where the Dexcom API will randomly rate-limit the device running this. I'm aware of this, and am looking into a fix.

1.1.4 12/16/25

• IMPORTANT! This may affect your apps! Made Dexcom.buffer default to 10 seconds. There is no real solution to this rate-limiting other than trying to not spam Dexcom's servers, so this package will by default now wait 5 minutes and 10 seconds (310 seconds) before requesting more glucose data again.
• Added DexcomGlucoseRequest class that's now a property of DexcomGlucoseRetrievalException. This tells you the request details, and has a toCurl function for reproduction.
• Make account ID an optional parameter, to optionally save time fetching the account ID automatically.
• Apparently the session token would never get refreshed, I've never had problems though, but I (maybe) fixed it.
• Added Dexcom.setLoggerCallback for controlling debug logs.
• Improved documentation.
