respect_24_hour 0.0.2

Flutter Plug-In for checking whether the device is using 24-hour time.

respect_24_hour

This project makes it possible to check whether the device is using 12 or 24 hour time.

Supported Platforms

• Android API 16+ (4.1+, the minimum version supported by Flutter).
• iOS 8.0+ (the minimum version supported by Flutter).

Getting Started

There is only one getter which is static and can be called anywhere.

//returns bool indicative of whether the device is using 24-hour time format
await Respect24Hour.get24HourFormat;

Troubleshooting - iOS

Xcode 10, Flutter and Swift sometimes don't play along well.

Why is it happening:

When using swift code in pods without swift code in the app itself, such error might occur.

Solution:

Add a dummy .swift file to your project using XCode and when promted, agree to add a Briding-Header.

"'respect_24_hour/respect_24_hour-Swift.h' file not found" Error

Example error log:

.../.pub-cache/hosted/pub.dartlang.org/respect_24_hour-0.0.1/ios/Classes/Respect24HourPlugin.m:2:9: 'respect_24_hour/respect_24_hour-Swift.h' file not found

Why is it happening:

XCode 10 works differently with swift and objective-c files and sometimes the autogenerated file used for including swift code in objective-c files is referenced without package.

Solution:

Delete the 'respect_24_hour/' part from the error causing line - 'respect_24_hour/respect_24_hour-Swift.h'.
Result: respect_24_hour-Swift.h
