Build(deps): Bump flow-parser from 0.142.0 to 0.201.0

[dependabot]

Bumps flow-parser from 0.142.0 to 0.201.0.

Release notes

Sourced from flow-parser's releases.

v0.201.0

Local Type Inference:

• Local Type Inference is a rewrite of Flow’s type inference algorithm. This change makes Flow’s inference behavior more reliable and predictable. It replaces a global inference scheme that Flow has relied on since its inception and that has often been the culprit of confusing action-at-a-distance behavior, in exchange for modestly increased type annotations. It is now enabled by default! See this blog post for more details on the new system and steps to upgrade your project.

Likely to cause new Flow errors:

• When a variable is initialized at declaration, subsequent assignment in a conditional branch will no longer cause later reads to get a union type. This is already the case if the variable is annotated. As a result of this change, you might get new type errors. Example
• When a variable is uninitialized or initialized to null, we use all the assignments to the variables as its initial type. We now no longer consider assignments from a child generic function. As a result, you might get new invalid-declaration errors. Example
• Fix object value rest. It will now error if attempting to read a write-only or setter-only property (it reads while copying the properties). Additionally, the resulting rest object will no longer preserve read-only variance (as it is a copy).
• The type utility $Partial will now preserve the variance of the input object type's properties. For example, if the the input was a read-only object, now that output will also be a read-only object (with optional properties).
• string and symbol are no longer subtypes of an interface
• Error on with statements in non-strict mode. It was already a syntax error in strict mode.

New Features:

• A native Apple Silicon precompiled binary is now available via the GitHub Releases page. It is not yet available via flow-bin. Internally, we see about 2X faster performance than using Rosetta, and 4X faster performance than on actual Intel Macs.
• Add local variable renaming capabilities to the LSP
• Add "Find All References" functionality to the LSP for showing local references
• JSDoc autocomplete will automatically trigger after typing /**
• Add option for automatically closing JSX tags in the IDE
• Hovering in the IDE now shows both the unevaluated and evaluated type of the target expression.
• Add use_mixed_in_catch_variables config option that makes catch variables default to mixed instead of any
• Rename $Partial utility type to Partial. $Partial will continue working as an alias for at least one more version - use that period of time to codemod it to Partial.
• Add the Required utility type. It does the opposite of Partial: it makes optional properties required in object types.
• Improve error when attempting to call Object.values on a Flow Enum, to point the user to using .members()
• Improve error when using number and boolean primitives as a subtype of an interface
• Improve error on tuple arity mismatch

Notable bug fixes:

• Fix a bug preventing annotation hints from being used in tagged template expressions. This fix may get rid of some underconstrained-implicit-instantiation errors that were otherwise impossible to fix.
• Fix error when autocompleting the method stub for a function type without parameter names
• Document highlight in the IDE now correctly highlights destructured object keys
• Autocomplete can suggest literals when the target type is $Keys

flow-upgrade:

• Add codemod to convert usage of the $Shape utility type to Partial. It is possible that this will create type errors that you will have to resolve.
• Add codemod to rename $Partial to Partial

Misc:

• Remove unused-promise-in-async-scope and unused-promise-in-sync-scope. They can be enabled with unused-promise.
• Remove --evaluate-type-destructors flag from type-at-pos command
• Add flow save-state --scm flag to ease creation of SCM-aware saved states

Parser:

• Fix missing decorators on class fields
• Make infer a reserved word in types

v0.200.1

Notable bug fixes: We fixed a bug that causes spurious Array is not an array errors in try-flow. Example
