The details

Resolves

Fixes #2506

Proposed Changes

In JavascriptGenerator.prototype.init and DartGenerator.prototype.init, use this.getVariableName(variables[i].getId()) instead of directly querying this.nameDB_.getName(variables[i].getId(), NameType.VARIABLE).

Reason for Changes

When a developer subclasses JavascriptGenerator or DartGenerator and overrides getVariableName() to customize how variable identifiers are formatted or generated, the variable declaration list (var ...;) in init() was previously bypassing getVariableName() and reading from nameDB_ directly.
This change ensures that variable declarations respect getVariableName(), aligning JavaScript and Dart generators with the existing pattern already used in PythonGenerator.prototype.init.

Test Coverage

Added unit tests in packages/blockly/tests/mocha/generator_test.js:

• Subclassed JavascriptGenerator, DartGenerator, and PythonGenerator with an overridden getVariableName().
• Verified that variable declarations generated in init() use the custom names returned by getVariableName().
• Verified all 25 mocha generator tests pass.
• Verified npm run lint and npm run format pass cleanly.

Documentation

None needed; internal generator consistency fix preserving existing public APIs.
