Description

Hey mattermost team, wonder if anyone hit this before on Android device.

More context on how we use it, we are using it as uncontrolled input like how bluesky is using it.

Will wanna identify if it's a library issue or my implementation issue.

Please let me know if any more information is needed.

Sample code on how I'm using it

    const pasteInputRef = useRef<PasteInputRef>(null);

    useImperativeHandle(ref, () => ({
        focus: () => {
            pasteInputRef.current?.focus();
        },
        blur: () => {
            pasteInputRef.current?.blur();
        },
        clear: () => {
            pasteInputRef.current?.clear();
        },
    }));

    return (
        <View style={containerStyle}>
            <PasteInput
                ref={pasteInputRef}
                multiline
                maxLength={500}
                style={[styles.input, disabled && styles.disabled, inputStyle]}
                onChangeText={onChangeText}
                onPaste={() => {}}
                autoCorrect
                pointerEvents={disabled ? 'none' : 'auto'}
                caretHidden={disabled}
                editable={!disabled}
                readOnly={disabled}
                focusable={!disabled}
                placeholderTextColor={disabled ? colorScheme['content-disabled'] : colorScheme['content-placeholder']}
                allowFontScaling={false}
                selectionColor={inputSelectionColor}
                selectionHandleColor={androidInputSelectionHandleColor}
                cursorColor={androidInputCursorColor}
            >
            {children}
            </PasteInput>
        </View>
    );

Research direction

Start by inspecting PasteInputEditText.onCreateInputConnection at line 58 and review the supplied uncontrolled React Native usage. Reproduce the Sentry stack trace on Android with the sample props, then determine whether the failure is in the library or the integration. Done should include a confirmed cause and a verified resolution, but the issue does not define expected behavior or test coverage.
