研究方向

從 TextInput onSubmitEditing 型別以及 React Native 0.87 使用的 NativeSyntheticEvent 定義開始。重現 issue 中嚴格的 TypeScript 指派，然後將其與 React 的 BaseSyntheticEvent 型別進行比較。完成標準是：所回報的 handler 在不弱化相關事件型別的情況下相容，並且針對所示範例有回歸檢查。

描述

Needs: Triage :mag: p: Callstack Partner
Description

My team uses unified codebase that share web and native code, so that is why a BaseSyntheticEvent event was used here.

import type {BaseSyntheticEvent} from 'react';

<TextInput onSubmitEditing={
  (event: BaseSyntheticEvent) => {
        event.bubbles; // boolean | undefined 
         // error: BaseSyntheticEvent require `boolean` only type
  }} 
/>

this issue doesn't not exist in prev. RN versions
