ImageWidget
Trả về hình ảnh tương ứng với imageUrl có thể là một URL hoặc một đường dẫn tới file ảnh trong thư mục assets, hoặc là đường dẫn trỏ tới file trong máy.
Intl
The Intl class provides a common entry point for internationalization related tasks. An Intl instance can be created for a particular locale and used to create a date format via anIntl.date(). Static methods on this class are also used in message formatting.
KeyboardDismisser
A widget that can dismiss the keyboard when performing a gesture.
KeyboardVisibilityBuilder
Calls builder on keyboard close/open. https://stackoverflow.com/a/63241409/1321917
LoadingWidget
LogEvent
LogFilter
An abstract filter of log messages.
LogfmtPrinter
Outputs a logfmt message:
Logger
Use instances of logger to send log messages to the LogPrinter.
LogOutput
Log output receives a OutputEvent from LogPrinter and sends it to the desired destination.
LogPrinter
An abstract handler of log events.
MemoryOutput
Buffers OutputEvents.
MicroMoney
Used primarily for currency formatting, this number-like class stores millionths of a currency unit, typically as an Int64.
MultiImageStreamCompleter
An ImageStreamCompleter with support for loading multiple images.
MultiOutput
Logs simultaneously to multiple LogOutput outputs.
Bọc widget trong một Navigator riêng biệt, để ví dụ replace nó với 1 widget khác thì sẽ mất toàn bộ các widget và các dialog đang hiện trong Navigator đó, thích hợp dùng ở màn hình login
NumberFormat
Provides the ability to format a number in a locale-specific way.
OutputEvent
PrefixPrinter
A decorator for a LogPrinter that allows for the prepending of every line in the log output with a string for the level of that log. For example:
PrettyPrinter
Default implementation of LogPrinter.
ProductionFilter
Prints all logs with level >= Logger.level even in production.
ShimmerBox
Trả về một Widget có kích thước là width và height được áp dụng sẵn hiệu ứng từ thư viện shimmer.
SimplePrinter
Outputs simple log messages:
StreamOutput
TextDirection
Represents directionality of text.
TextStyles

Typedefs

ImageWidgetBuilder = Widget Function(BuildContext context, ImageProvider<Object> imageProvider)
Builder function to create an image widget. The function is called after the ImageProvider completes the image loading.
LoadingErrorWidgetBuilder = Widget Function(BuildContext context, String url, Object error)
Builder function to create an error widget. This builder is called when the image failed loading, for example due to a 404 NotFound exception.
LogCallback = void Function(LogEvent event)
OutputCallback = void Function(OutputEvent event)
PlaceholderWidgetBuilder = Widget Function(BuildContext context, String url)
Builder function to create a placeholder widget. The function is called once while the ImageProvider is loading the image.
ProgressIndicatorBuilder = Widget Function(BuildContext context, String url, DownloadProgress progress)
Builder function to create a progress indicator widget. The function is called every time a chuck of the image is downloaded from the web, but at least once during image loading.
