export function appendStatementAfterImports(
  source: SourceFile,
  statement: string,
  apply = true
) {
  const imports = source

    .getChildrenOfKind(SyntaxKind.ImportDeclaration);

  let appendIdx: number;

  if (!imports.length) {
    appendIdx = 0;
  } else {
    appendIdx =
      source.getLastChildByKind(SyntaxKind.ImportDeclaration).getChildIndex() +
      1;

    writer.write(statement);
  });
  apply && source.saveSync();
}

// 新增具名导入成员
// 在importSpec不存在时，会新增一条具名导入
// 会过滤已存在的具名导入成员
