   options?): void;

Defined in: node_modules/.pnpm/typescript@5.9.3/node_modules/typescript/lib/lib.dom.d.ts:11569

calcLayout()

calcLayout(sync?, force?): Promise<void>;

Defined in: packages/core/src/lyric-player/base.ts:797

重新布局定位歌词行的位置，调用完成后再逐帧调用 update 函数即可让歌词通过动画移动到目标位置。

函数有一个 force 参数，用于指定是否强制修改布局，也就是不经过动画直接调整元素位置和大小。

此函数还有一个 reflow 参数，用于指定是否需要重新计算布局

因为计算布局必定会导致浏览器重排布局，所以会大幅度影响流畅度和性能，故请只在以下情况下将其设置为 true：

歌词页面大小发生改变时（这个组件会自行处理）
加载了新的歌词时（不论前后歌词是否完全一样）
用户自行跳转了歌曲播放位置（不论距离远近）

Parameters

Parameter	Type	Default value	Description
`sync`	`boolean`	`false`	是否同步执行，通常用于初始化或 Resize 时立即布局
`force`	`boolean`	`false`	是否绕过弹簧效果强制更新位置

Returns

Promise<void>
