VariableSubstitution class

Represents an interpolation of a variable value in a message. We expect this to be specified as an index into the list of variables, or else as the name of a variable that exists in arguments and we will compute the variable name or the index based on the value of the other.

Constructors

VariableSubstitution(int? _index, Message? parent)
VariableSubstitution.named(String name, Message? parent)
Create a substitution based on the name rather than the index. The name may have been used as all upper-case in the translation tool, so we save it separately and look it up case-insensitively once the parent (and its arguments) are definitely available.

Properties

arguments → dynamic
We find the arguments from the top-level MainMessage and use those to do variable substitutions. MainMessage overrides this to return the actual arguments.
no setterinherited
examples → dynamic
We find the examples from the top-level MainMessage and use those when writing out variables. MainMessage overrides this to return the actual examples.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
index → int?
no setter
name → String
The name of the top-level MainMessage.
no setterinherited
parent ↔ Message?
All Messages except a MainMessage are contained inside some parent, terminating at an Intl.message call which supplies the arguments we use for variable substitutions.
getter/setter pairinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
variableName → String?
The name of the variable in the parameter list of the containing function. Used when generating code for the interpolation.
no setter
variableNameFromParser ↔ String
The original variable name we get from parsing.

Methods

checkArgs(NamedExpression? args, List<String> parameterNames) → bool
Verify that the args argument matches the method parameters and isn't, e.g. passing string names instead of the argument values.
inherited
checkValidity(MethodInvocation node, List arguments, String? outerName, FormalParameterList outerArgs, {bool nameAndArgsGenerated = false, bool examplesRequired = false}) → String?
Verify that this looks like a correct Intl.message/plural/gender/... invocation.
inherited
escapeAndValidateString(String value) → String
Escape the string for use in generated Dart code.
inherited
expanded([Function? f = _nullTransform]) → String?
Expand this string out into a printed form. The function f will be applied to any sub-messages, allowing this to be used to generate a form suitable for a wide variety of translation file formats.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toCode() → String
Return a string representation of this message for use in generated Dart code.
override
toJson() → Object?
Return a JSON-storable representation of this message which can be interpolated at runtime.
override
toString() → String
A string representation of this object.
override
validate() → void
Verify that a constructed message is valid.

Operators

operator ==(Object other) → bool
The equality operator.
