shiftXDescription carries the wrong translator description in both files. The description text was copied from upDescription and says "select previous item", while defaultMessage is 'Select current item'. The TS module and its Flow sidecar must stay identical, so correct both.

Flow type checker .js.flow files@flowpragma all=true behavior official documentation💡 Result:
In the Flow type checker,
.js.flowfiles serve as declaration files that provide type definitions separate from their corresponding implementation files [1]. When a.js.flowfile exists in the same directory as a.jsfile of the same name, Flow shadows (ignores) the implementation file and uses the declarations in the.js.flowfile instead [1][2]. Regarding theall=trueconfiguration and@flowpragma: 1. All=true configuration: By settingall=truein the[options]section of your.flowconfigfile, you instruct Flow to type-check every file in your project, regardless of whether they contain a@flowpragma [3][4]. The default value for this setting isfalse, meaning Flow only checks files with the@flowannotation by default [3]. 2. Pragma behavior in.js.flow files: While.js.flowfiles act as declarations, it is recommended practice to include the//@flowpragma at the top of these files to ensure they are properly recognized and processed by the Flow type checker [5][6]. Without the pragma, Flow may treat imports from the associated module as `any`, effectively bypassing type safety for that module [5][6]. 3. Interaction: When `all=true` is enabled, Flow's behavior changes such that it no longer relies exclusively on the presence of the `@flow` pragma to decide whether to check a file [3][4]. However, even with `all=true`, using standard Flow annotations (like `// `@flowor//@flowstrict) remains the best way to explicitly manage type-checking status and linting rules on a per-file basis [7][8]. Note thatallis not a lint rule and cannot be set via in-file comments; it must be configured in the.flowconfig[9].Citations:

In the context of the Flow type checker,.js.flow files and the
@flowannotation serve two distinct purposes regarding type definitions and file processing..js.flow Files A.js.flow file is a declaration file used to define types for a module separately from its corresponding JavaScript implementation [1]. When a.js.flow file exists in the same directory as a file with the same name (e.g., File.js.flow alongside File.js), Flow ignores the implementation file and uses the declaration file for type checking [1]. This is useful for adding type definitions to generated code, files that must remain plain JavaScript, or modules where you want to override existing types [1]. If an implementation file is missing, the.js.flow file is treated as the module itself [1].@flowAnnotation The@flowannotation is a pragma placed at the top of a JavaScript file. It serves as a directive to the Flow type checker to process that specific file [1]. Without this pragma (or a configuration that treats files as Flow-enabled by default), Flow will typically skip the file during its analysis.Citations:

site:github.com/facebook/flow ".js.flow" "all=true" pragma checked💡 Result:
In the context of Flow, the terms you mentioned refer to specific configuration strategies for type checking:.js.flow files These are source files that contain Flow type definitions. They are typically used for library authors who wish to ship Flow types alongside their JavaScript code [1]. When you publish a package to npm, Flow can use a.js.flow file (e.g., if you have index.js, you can provide index.js.flow) to understand the types of that module without needing to parse the actual implementation file [1]. This allows for cleaner, interface-only type definitions. all=true This is a configuration option set within the [options] section of your.flowconfig file [2]. - When all=true is enabled, Flow will type-check all files in your project by default, even if they do not contain the /*
@flow/ pragma header at the top of the file [2]. - This effectively treats every JavaScript file as if it were annotated with@flow, which can be useful for enforcing strict type coverage across an entire codebase without having to manually add the header to every file [2]. Pragma (e.g.,@flow) A pragma is a special comment, such as /@flow*/ or //@flow, placed at the top of a JavaScript file to instruct the Flow engine to type-check that specific file [2]. When all=true is NOT set, only files containing this pragma are checked. When all=true IS set, the pragma becomes largely redundant for internal files, though it is still used by many developers to explicitly signal intended type-checking status [2]. "checked" There is no standard Flow-specific pragma named "checked". If you are encountering this term in a configuration context, it may be a misremembered reference to the all=true setting (which enforces checking) or perhaps a custom comment style used in specific development environments or other static analysis tools (like TypeScript's@ts-check). In Flow, the enforcement of type checking is governed by the@flowpragma or the all=true global configuration [2].Citations:

Flow 0.95 .js.flow interface file without@flowpragma checked source code💡 Result:
In Flow version 0.95 (and throughout its history), a.js.flow interface file must include the //
@flowpragma to be correctly processed and used for type checking [1][2][3]. If a.js.flow file lacks the //@flowpragma, Flow will generally treat the corresponding module as untyped (often defaulting to any), meaning it will fail to enforce type safety or detect errors in the implementation imported into other Flow-enabled files [1][2][3]. While.js.flow files are explicitly recognized by Flow to provide type definitions for their corresponding.js implementation files, this mechanism relies on the file being opted into Flow's analysis via the standard pragma [1][2][4]. Without the pragma, Flow ignores the type definitions within the.js.flow file, which effectively defeats its purpose as a declaration file [1][2]. To ensure correct type checking, you should always include //@flowat the top of your.js.flow files [1][3].Citations:

site:github.com/facebook/flow/blob v0.95 js.flow flow pragma interface file💡 Result:
In Flow, a.js.flow file is a specialized interface file used to provide type definitions for a corresponding JavaScript file [1]. These files allow Flow to check against the provided type information instead of the implementation, which is useful for library definitions or when separating type declarations from source code. Key aspects regarding your query include: 1. Functionality: A.js.flow file serves as an interface file [1]. When Flow encounters a module import, it checks if a corresponding.js.flow file exists alongside the target JavaScript file. If found, Flow uses the types defined in the.js.flow file to type-check the usage of that module [1]. 2. Flow Pragma: Similar to standard JavaScript files in Flow,.js.flow files typically include the Flow pragma (e.g., /*
@flow*/) at the top of the file to signal that the file should be processed by the type checker [2][3][4]. Without this pragma, Flow may ignore the file depending on the project configuration [2][5]. 3. Context (v0.95): Flow v0.95 introduced various updates and bug fixes, including changes to JSON.stringify typing and other internal improvements [6][7]. While there were no breaking changes specifically re-defining the fundamental role of.js.flow files in this version, the version serves as a stable point for utilizing these interface files to manage complex type definitions or library boundaries. In practice, developers use.js.flow files to maintain strict separation between type declarations and runtime logic, ensuring that the type checker has explicit definitions even if the original source code is not fully typed or uses complex patterns that Flow cannot infer statically [1].Citations:
