如何在Uniapp 的App端使用AntV F2 #2070
Description
因为直接用f-vue，在app端遇到canvas的context报错问题。我目前对照f-vue项目中的index.ts文件，做了一个适配，但还是报错。该从哪里下手。
//#ifdef APP-PLUS
context = uni.createCanvasContext('f2-canvas-app', this);
returnObject = {
...props,
children: toRawChildren($slots),
};
//#endif
// #ifndef APP-PLUS
context = canvasEl.getContext('2d');
returnObject = {
...props,
// context 内部创建，不能被覆盖
context,
children: toRawChildren($slots),
};
错误信息：
