dart SKD のエラー・例外の一覧がなかったので。 https://api.dart.dev/stable/2.13.1/index.html
エラーと例外の違い
Dart には Exception と Error の型があり、また数多くのあらかじめ定義されたそれらの副型がある。無論自分自身の例外を定義することも可能である。しかしながら、Dart のプログラムは非 null オブジェクト（単に Exception と Error のオブジェクトでなく）を例外としてスローし得る。Error と Exception に関しては、基本的に Error とそのサブクラスはプログラム・エラーであり、そのプログラムは修正が必要である。一方非エラーの Exception は実行時エラーである。これは通常プログラムであらかじめスローされるのを防止出来ない。

エラー
AbstractClassInstantiationError
Error thrown when trying to instantiate an abstract class.
https://api.dart.dev/stable/2.1.1/dart-core/AbstractClassInstantiationError-class.html
ArgumentError
Error thrown when a function is passed an unacceptable argument.
https://api.dart.dev/stable/2.1.1/dart-core/ArgumentError-class.html
AssertionError
Error thrown by the runtime system when an assert statement fails.
https://api.dart.dev/stable/2.1.1/dart-core/AssertionError-class.html
AsyncError
Pair of error and stack trace. Returned by Zone.errorCallback.
https://api.dart.dev/stable/2.1.1/dart-async/AsyncError-class.html
CastError
Error thrown by the runtime system when a cast operation fails.
https://api.dart.dev/stable/2.1.1/dart-core/CastError-class.html
ConcurrentModificationError
Error occurring when a collection is modified during iteration.
Some modifications may be allowed for some collections, so each collection (Iterable or similar collection of values) should declare which operations are allowed during an iteration.
https://api.dart.dev/stable/2.1.1/dart-core/ConcurrentModificationError-class.html
CyclicInitializationError
Error thrown when a lazily initialized variable cannot be initialized.
A static/library variable with an initializer expression is initialized the first time it is read. If evaluating the initializer expression causes another read of the variable, this error is thrown.
https://api.dart.dev/stable/2.1.1/dart-core/CyclicInitializationError-class.html
FallThroughError
Error thrown when control reaches the end of a switch case.
The Dart specification requires this error to be thrown when control reaches the end of a switch case (except the last case of a switch) without meeting a break or similar end of the control flow.
https://api.dart.dev/stable/2.13.1/dart-core/FallThroughError-class.html
IndexError
A specialized RangeError used when an index is not in the range 0..indexable.length-1.
Also contains the indexable object, its length at the time of the error, and the invalid index itself.
https://api.dart.dev/stable/2.13.1/dart-core/IndexError-class.html
JsonCyclicError
Reports that an object could not be stringified due to cyclic references.
An object that references itself cannot be serialized by JsonCodec.encode/JsonEncoder.convert. When the cycle is detected, a JsonCyclicError is thrown.
https://api.dart.dev/stable/2.13.1/dart-convert/JsonCyclicError-class.html
JsonUnsupportedObjectError
Error thrown by JSON serialization if an object cannot be serialized.
The unsupportedObject field holds that object that failed to be serialized.
If an object isn't directly serializable, the serializer calls the toJson method on the object. If that call fails, the error will be stored in the cause field. If the call returns an object that isn't directly serializable, the cause is null.
https://api.dart.dev/stable/2.13.1/dart-convert/JsonUnsupportedObjectError-class.html
NoSuchMethodError
Error thrown by the default implementation of noSuchMethod on Object.
https://api.dart.dev/stable/2.13.1/dart-core/NoSuchMethodError-class.html
NullThrownError
Error thrown when attempting to throw null.
In null safe code, you are statically disallowed from throwing null, so this error will go away when non-null safe code stops being supported.
https://api.dart.dev/stable/2.13.1/dart-core/NullThrownError-class.html
OSError
An Exception holding information about an error from the operating system.
https://api.dart.dev/stable/2.13.1/dart-io/OSError-class.html
OutOfMemoryError
Error that the platform can use in case of memory shortage.
https://api.dart.dev/stable/2.13.1/dart-core/OutOfMemoryError-class.html
RangeError
Error thrown due to a value being outside a valid range.
https://api.dart.dev/stable/2.13.1/dart-core/RangeError-class.html
RemoteError
Description of an error from another isolate.
This error has the same toString() and stackTrace.toString() behavior as the original error, but has no other features of the original error.
https://api.dart.dev/stable/2.1.1/dart-isolate/RemoteError-class.html
RemoteError
Description of an error from another isolate.
This error has the same toString() and stackTrace.toString() behavior as the original error, but has no other features of the original error.
https://api.dart.dev/stable/2.13.1/dart-isolate/RemoteError-class.html
StateError
The operation was not allowed by the current state of the object.
Should be used when this particular object is currently in a state which doesn't support the requested operation, but other similar objects might, or the object might change its state to one which supports the operation. Example: Asking for list.first on a currently empty list. If the operation is never supported, consider using UnsupportedError instead.
This is a generic error used for a variety of different erroneous actions. The message should be descriptive.
https://api.dart.dev/stable/2.13.1/dart-core/StateError-class.html
TypeError
Error thrown by the runtime system when a dynamic type error happens.
https://api.dart.dev/stable/2.13.1/dart-core/TypeError-class.html
UnimplementedError
Thrown by operations that have not been implemented yet.
This Error is thrown by unfinished code that hasn't yet implemented all the features it needs.
If the class does not intend to implement the feature, it should throw an UnsupportedError instead. This error is only intended for use during development.
https://api.dart.dev/stable/2.13.1/dart-core/StackOverflowError-class.html
UnsupportedError
The operation was not allowed by the object.
This Error is thrown when an instance cannot implement one of the methods in its signature.
https://api.dart.dev/stable/2.13.1/dart-core/UnsupportedError-class.html
