Release Notes

v3.5.0

Compare Source

Language

• Breaking Change #​55418: The context used by the compiler to perform
  type inference on the operand of an await expression has been changed to
  match the behavior of the analyzer. This change is not expected to make any
  difference in practice.

• Breaking Change #​55436: The context used by the compiler to perform
  type inference on the right hand side of an "if-null" expression (e1 ?? e2)
  has been changed to match the behavior of the analyzer. change is expected to
  have low impact on real-world code. But in principle it could cause
  compile-time errors or changes in runtime behavior by changing inferred
  types. The old behavior can be restored by supplying explicit types.

Libraries

dart:core

• Breaking Change #​44876: DateTime on the web platform now stores
  microseconds. The web implementation is now practically compatible with the
  native implementation, where it is possible to round-trip a timestamp in
  microseconds through a DateTime value without rounding the lower
  digits. This change might be breaking for apps that rely in some way on the
  .microsecond component always being zero, for example, expecting only three
  fractional second digits in the toString() representation. Small
  discrepancies in arithmetic due to rounding of web integers may still occur
  for extreme values, (1) microsecondsSinceEpoch outside the safe range,
  corresponding to dates with a year outside of 1685..2255, and (2) arithmetic
  (add, subtract, difference) where the Duration argument or result
  exceeds 570 years.

dart:io

• Breaking Change #​55786: SecurityContext is now final. This means
  that SecurityContext can no longer be subclassed. SecurityContext
  subclasses were never able to interoperate with other parts of dart:io.

• A ConnectionTask can now be created using an existing Future<Socket>.
  Fixes #​55562.

dart:typed_data

• Breaking Change #​53785: The unmodifiable view classes for typed data
  have been removed. These classes were deprecated in Dart 3.4.

  To create an unmodifiable view of a typed-data object, use the
  asUnmodifiableView() methods added in Dart 3.3.

• Added superinterface TypedDataList to typed data lists, implementing both
  List and TypedData. Allows abstracting over all such lists without losing
  access to either the List or the TypedData members.
  A ByteData is still only a TypedData, not a list.

dart:js_interop

• Breaking Change #​55508: importModule now accepts a JSAny instead
  of a String to support other JS values as well, like TrustedScriptURLs.

• Breaking Change #​55267: isTruthy and not now return JSBoolean
  instead of bool to be consistent with the other operators.

• Breaking Change ExternalDartReference no longer implements Object.
  ExternalDartReference now accepts a type parameter T with a bound of
  Object? to capture the type of the Dart object that is externalized.
  ExternalDartReferenceToObject.toDartObject now returns a T.
  ExternalDartReferenceToObject and ObjectToExternalDartReference are now
  extensions on T and ExternalDartReference<T>, respectively, where T extends Object?. See #​55342 and #​55536 for more details.

• Fixed some consistency issues with Function.toJS across all compilers.
  Specifically, calling Function.toJS on the same function gives you a new JS
  function (see issue #​55515), the maximum number of arguments that are
  passed to the JS function is determined by the static type of the Dart
  function, and extra arguments are dropped when passed to the JS function in
  all compilers (see #​48186).

Tools

Linter

• Added the [unintended_html_in_doc_comment][unintended_html_in_doc_comment] lint.
• Added the [invalid_runtime_check_with_js_interop_types][invalid_runtime_check_with_js_interop_types] lint.
• Added the [document_ignores][document_ignores] lint.

Pub

• New flag dart pub downgrade --tighten to restrict lower bounds of
  dependencies' constraints to the minimum that can be resolved.

Dart Runtime

• The Dart VM only executes sound null safe code, running of unsound null
  safe code using the option --no-sound-null-safety has been removed.

• Dart_NewListOf and Dart_IsLegacyType functions are
  removed from Dart C API.

• Dart_DefaultCanonicalizeUrl is removed from the Dart C API.
