Is this package support Dart 3 compatible? I couldn't see that badge in pub.dev
the function is expected to return true only if the dateTime refers to Today only, while it returns true for same day but different month and year.
I know it is a simple thing but the function name gives that expectation.
Thank You.

onAccept of showConfirmDialogCustom throw new NoSuchMethodError.withInvocation(this, invocation);
Hello,
how can I add showConfirmDialogCustom (or other Dialog) inside onAccept function of another showConfirmDialogCustom ?
Thank you
Hello,
First of all; great package. It's very useful!
I noticed a mistake.
/// Returns true if given date is yesterday
bool get isYesterday {
final now = DateTime.now();
final yesterday = DateTime(now.year, now.month, now.day - 1);
return DateTime(now.year, now.month, now.day - 1) == yesterday;
}
I think it should be something like this.
/// Returns true if given date is yesterday
bool get isYesterday {
final now = DateTime.now();
final yesterday = DateTime(now.year, now.month, now.day - 1);
return DateTime(this.year, this.month, this.day) == yesterday;
}
Thanks!

Hi,
can you upgrade the flutter version because some dependencies on this library is not updated to be compatible with the new Flutter version .
Kind regards
Hi friends, thanks for your great package, I'm using it and it is showing error , I tried a lot of things nothing seems to work :( .
Hello, I'm facing an issue with this package. This is the error I'm getting. Kindly, help me asap.
The plugin nb_utils doesn't have a main class defined in
E:\development\flutter.pub-cache\hosted\pub.dartlang.org\nb_utils-4.4.9\android\src\main\java\com\nb\nb_utils\NbUtilsPlugin.java or
E:\development\flutter.pub-cache\hosted\pub.dartlang.org\nb_utils-4.4.9\android\src\main\kotlin\com\nb\nb_utils\NbUtilsPlugin.kt. This is likely to due to an incorrect androidPackage: com.nb.nb_utils or mainClass entry inthe plugin's pubspec.yaml.
If you are the author of this plugin, fix the androidPackage entry or move the main class to any of locations
used above. Otherwise, please contact the author of this plugin and consider using a different plugin in the
meanwhile.

Hi, when facing such a problem here is how to fix it.
change your minSdkVersion under app/build.grade to 21 or higher
Then run Flutter clean and run your project
build.gradle needs namespace:
android { namespace "com.nb.nb_utils" }
