<itemvalue="On Linux and OS X a normal exit code will be a positive value in the range `[0..255]`. If the process was terminated due to a signal the exit code will be a negative value in the range `[-255..-1]`, where the absolute value of the exit code is the signal number. For example, if a process crashes due to a segmentation violation the exit code will be -11, as the signal SIGSEGV has the number 11."/>
<itemvalue="Compares two maps for element-by-element equality. Returns true if the maps are both null, or if they are both non-null, have the same length, and contain the same keys associated with the same values. Returns false otherwise. If the elements are maps, lists, sets, or other collectionscomposite objects, then the contents of those elements are not compared element by element unless their equality operators ([Object.==]) do so. For checking deep equality, consider using the [DeepCollectionEquality] class. See also: [setEquals], which does something similar for sets. [listEquals], which does something similar for lists."/>
<itemvalue="Tools that recognize pragma hints should pick a pragma prefix to identify the tool. They should recognize any hint with a [name] starting with their prefix followed by `:` as if it was intended for that tool. A hint with a prefix for another tool should be ignored (unless compatibility with that other tool is a goal)."/>
<itemvalue="Marks a feature as [Deprecated] until the next release."/>
<itemvalue="Create a deprecation annotation which specifies the migration path and expiration of the annotated feature. The [message] argument should be readable by programmers, and should state an alternative feature (if available) as well as when an annotated feature is expected to be removed."/>
<itemvalue="This constructor is only guaranteed to work when invoked as `const`. It may work as a non-constant invocation on some platforms which have access to compiler options at run-time, but most ahead-of-time compiled platforms will not have this information."/>
<itemvalue="The compilation configuration environment is not the same as the environment variables of a POSIX process. Those can be accessed on native platforms using `Platform.environment` from the `dart:io` library."/>
<itemvalue="The base class for all protobuf message types. The protoc plugin generates subclasses providing type-specific properties and methods. Public properties and methods added here should also be added to `GeneratedMessage_reservedNames` and should be unlikely to be used in a proto file."/>

<itemvalue="A hinge joint that rotates along the axis and has a limited range specified by the upper and lower limits."/>
<itemvalue="A continuous hinge joint that rotates around the axis and has no upper and lower limits."/>
<itemvalue="This is not really a joint because it cannot move. All degrees of freedom are locked. This type of joint does not require the <axis>, <calibration>, <dynamics>, <limits> or <safety_controller>"/>
<itemvalue="Whether a tick should be scheduled. If this is true, then calling [scheduleTick] should succeed. Reasons why a tick should not be scheduled include: A tick has already been scheduled for the coming frame. The ticker is not active ([start] has not been called). The ticker is not ticking, e.g. because it is [muted] (see [isTicking])."/>
<itemvalue="Whether this selection has disambiguated its base and extent. On some platforms, the base and extent are not disambiguated until the first time the user adjusts the selection. At that point, either the start or the end of the selection becomes the base and the other one becomes the extent and is adjusted."/>
<itemvalue="This section identifies this Flutter project as a plugin project. The 'pluginClass' specifies the class (in Java, Kotlin, Swift, Objective-C, etc.) which should be registered in the plugin registry. This is required for using method channels. The Android 'package' specifies package in which the registered class is. This is required for using method channels on Android. The 'ffiPlugin' specifies that native code should be built and bundled. This is required for using `dart:ffi`. All these are used by the tooling to maintain consistency when adding or updating assets for this project."/>
<itemvalue="The string without any leading and trailing whitespace. If the string contains leading or trailing whitespace, a new string with no leading and no trailing whitespace is returned: ```dart final trimmed = '\tDart is fun\n'.trim(); print(trimmed); 'Dart is fun' ``` Otherwise, the original string itself is returned: ```dart const string1 = 'Dart'; final string2 = string1.trim(); 'Dart' print(identical(string1, string2)); true ``` Whitespace is defined by the Unicode White_Space property (as defined in version 6.2 or later) and the BOM character, 0xFEFF. Here is the list of trimmed characters according to Unicode version 6.3: ```plaintext 0009..000D ; White_Space Cc <control-0009>..<control-000D> 0020 ; White_Space Zs SPACE 0085 ; White_Space Cc <control-0085> 00A0 ; White_Space Zs NO-BREAK SPACE 1680 ; White_Space Zs OGHAM SPACE MARK 2000..200A ; White_Space Zs EN QUAD..HAIR SPACE 2028 ; White_Space Zl LINE SEPARATOR 2029 ; White_Space Zp PARAGRAPH SEPARATOR 202F ; White_Space Zs NARROW NO-BREAK SPACE 205F ; White_Space Zs MEDIUM MATHEMATICAL SPACE 3000 ; White_Space Zs IDEOGRAPHIC SPACE FEFF ; BOM ZERO WIDTH NO_BREAK SPACE ``` Some later versions of Unicode do not include U+0085 as a whitespace character. Whether it is trimmed depends on the Unicode version used by the system."/>
